PROCEDURE
All contributions will be peer reviewed and only those deemed worthy and suitable will be accepted for publication. The Editor has the final decision. To facilitate the reviewing process, authors are encouraged to suggest up to three persons competent to review their manuscript. Such suggestions will be taken into consideration but not always accepted. If authors would prefer a specific person not be a reviewer, this should be announced. The Cover Letter must be accompanied by these suggestions.

Manuscripts requiring revision should be returned according to the requirement of the Editor, within 60 days upon reception of the reviewing comments by e-mail.

The Journal maintains its policy and takes the liberty of correcting the English as well as false content of manuscripts provisionally accepted for publication in the first stage of reviewing process. In this second stage of manuscript preparation by JSCS Editorial Office, the author(s) may be required to supply some additional clarifications and corrections. This procedure will be executed during copyediting actions, with a demand to author(s) to perform corrections of unclear parts before the manuscript would be published OnLine as finally accepted manuscript (OnLine First Section of the JSCS website). Please note that the manuscript can receive the status of final rejection if the authors corrections would not be satisfactory.

When finally accepted manuscript is ready for printing, the corresponding author will receive a request for proof reading, which should be performed within 2 days. Failure to do so will be taken as the authors are in agreement with any alteration which may have occurred during the preparation of the manuscript for printing.
Accepted manuscripts of active members of the Serbian Chemical Society (all authors) have publishing priority.

MANUSCRIPT PRESENTATION
Manuscripts should be typed in English (either standard British or American English, but consistent throughout) with 1.5 spacing (12 points Times New Roman; Greek letters in the character font Symbol) in A4 format leaving 2.5 cm for margins. For Regional specific, non-standard characters that may appear in the text, save documents with Embed fonts Word option: Save as -> (Tools) -> Save Options… -> Embed fonts in the text.

The authors are requested to seek the assistance of competent English language expert, if necessary, to ensure their English is of a reasonable standard. The Serbian Chemical Society can provide this service in advance of submission of the manuscript. If this service is required, please contact the office of the Society by e-mail (jscs-info@shd.org.rs).

Tables, figures and/or schemes must be embedded in the main text of the manuscript and should follow the paragraph in which they are mentioned for the first time. Tables must be prepared with the aid of the WORD table function, without vertical lines. The minimum size of the font in the tables should be 10 pt. Table columns must not be formatted using multiple spaces. Table rows must not be formatted using any returns (enter key; return key) and are limited to 12 cm length. Tables should not be incorporated as graphical objects. Footnotes to tables should follow them and are to be indicated consequently (in a single line) in superscript letters and separated by semi-column.  Table caption must be placed above corresponding Table, while Captions of the Illustrations (Figs. Schemes...) must follow the corresponing item. The captions, either for Tables or Illustrations, should make the items comprehensible without reading of the main text (but clearly referenced in), must follow numerical order (Roman for Tables, Arabic for Illustrations), and should not be provided on separate sheats or as separate files.

High resolution Illustrations (named as Fig. 1, Fig. 2… and/or Scheme 1, Scheme 2…) in TIF or EPS format (JPG format is acceptable for colour and greyscale photos, only) must be additionally uploaded as a separate files or one archived (.zip, .rar or .arj) file.

DESIGNATION OF PHYSICAL QUANTITIES AND UNITS
IUPAC recommendations for the naming of compounds should be followed. SI units, or other permissible units, should be employed. The designation of physical quantities must be in italic throughout the text (including figures, tables and equations), whereas the units and indexes (except for indexes having the meaning of physical quantities) are in upright letters. They should be in Times New Roman font. In graphs and tables, a slash should be used to separate the designation of a physical quantity from the unit (example: p / kPa, j / mA cm^-2, T₀ / K, t / h, ln (j / mA cm^-2)…). Designations such as: p (kPa), t [min]…, are not acceptable. However, if the full name of a physical quantity is unavoidable, it should be given in upright letters and separated from the unit by a comma (example: Pressure, kPa; Temperature, K; Current density, mA cm^-2…).. Please do not use the axes of graphs for additional explanations; these should be mentioned in the figure captions and/or the manuscript (example: "pressure at the inlet of the system, kPa" should be avoided). The axis name should follow the direction of the axis (the name of y‑axis should be rotated by 90°). Top and right axes should be avoided in diagrams, unless they are absolutely necessary.

Latin words, as well as the names of species, should be in italic, as for example: i.e., e.g., in vivo, ibid, Calendula officinalis L., etc. The branching of organic compound should also be indicated in italic, for example, n-butanol, tert-butanol, etc.

Decimal numbers must have decimal points and not commas in the text (except in the Serbian abstract), tables and axis labels in graphical presentations of results. Thousands are separated, if at all, by a comma and not a point.

Mathematical and chemical equations should be given in separate lines and must be numbered, Arabic numbers, consecutively in parenthesis at the end of the line. All equations should be embedded in the text except when they contain graphical elements (tables, figures, schemes and formulae). Complex equations (fractions, integrals, matrix…) should be prepared with the aid of the Microsoft Equation 3.0 (or higher) or MathType (Do not use them to create simple equations and labels). Using the Insert -> Equation option, integrated in MS Office 2010 and MS Office 2013, as well as insertion of equation objects within paragraph text IS NOT ALLOWED.

The EXPERIMENTAL section should give the purity and source of all employed materials, as well as details of the instruments used. The employed methods should be described in sufficient detail to enable experienced persons to repeat them. Standard procedures should be referenced and only modifications described in detail.

On no account should results be included in the experimental section.

Chemistry
Detailed informations about instruments and general experimental techniques should be given in all necessary details. If special treatment for solvents or chemical purification were applied that must be emphasized.
Example: Melting points were determined on a Boetius PMHK or a Mel-Temp apparatus and were not corrected. Optical rotations were measured on a Rudolph Research Analytical automatic polarimeter, Autopol IV in dichloromethane (DCM) or methanol (MeOH) as solvent. IR spectra were recorded on a Perkin-Elmer spectrophotometer FT-IR 1725X. ¹H and ¹³C NMR spectra were recorded on a Varian Gemini-200 spectrometer (at 200 and 50 MHz, respectively), and on a Bruker Ultrashield Advance III spectrometer (at 500 and 125 MHz, respectively) employing indicated solvents (vide infra) using TMS as the internal standard. Chemical shifts are expressed in ppm (δ / ppm) values and coupling constants in Hz (J / Hz). ESI-MS spectra were recorded on Agilent Technologies 6210 Time-Of-Flight LC-MS instrument in positive ion mode with CH₃CN/H₂O 1/1 with 0.2 % HCOOH as the carrying solvent solution. Samples were dissolved in CH₃CN or MeOH HPLC grade purity). The selected values were as follows: capillary voltage = 4 kV, gas temperature = 350 °C, drying gas flow 12 L min⁻¹, nebulizer pressure = 310 kPa, fragmentator voltage = 70 V.The elemental analysis was performed on the Vario EL III- C,H,N,S/O Elemental Analyzer (Elementar Analysensysteme GmbH, Hanau-Germany). Thin-layer chromatography (TLC) was performed on precoated Merck silica gel 60 F254 and RP-18 F254 plates. Column chromatography was performed on Lobar LichroPrep Si 60 (40-63 µm), RP-18 (40-63 µm) columns coupled to a Waters RI 401 detector, and on Biotage SP1 system with UV detector and FLASH 12+, FLASH 25+ or FLASH 40+ columns pre packed with KP-SIL [40-63 µm, pore diameter 6 nm (60 Å)], KP-C18-HS (40-63 µm, pore diameter 9 nm (90 Å) or KP-NH [40-63 µm, pore diameter 10 nm (100 Å)] as adsorbent. Compounds were analyzed for purity (HPLC) using a Waters 1525 HPLC dual pump system equipped with an Alltech, Select degasser system, and dual λ 2487 UV-VIS detector. For data processing, Empower software was used (methods A and B). Methods C and D: Agylent Тechnologies 1260 Liquid Chromatograph equipped with Quat Pump (G1311B), Injector (G1329B) 1260 ALS, TCC 1260 (G1316A) and Detector 1260 DAD VL+ (G1315C). For data processing, LC OpenLab CDS ChemStation software was used. For details, see Supporting Information.

1. Synthesis experiments
Each paragraph describing a synthesis experiment should begin with the name of the product and any structure number assigned to the compound in the Results and Discussions section. Thereafter, the compound should be identified by its structure number. Use of standard abbreviations or unambiguous molecular formulas for reagents and solvents, and of structure numbers rather than chemical names to identify starting materials and intermediates, is encouraged.
When a new or improved synthetic method is described, the yields reported in key experimental examples, and yields used for comparison with existing methods, should represent amounts of isolated and purified products, rather than chromate­gra­phically or spectroscopically determined yields. Reactant quantities should be reported in weight and molar units and for product yields should be reported in weight units; percentage yields should only be reported for materials of demonstrated purity. When chromatography is used for product purification, both the support and solvent should be identified.

2. Microwave experiments
Reports of syntheses conducted in microwave reactors must clearly indicate whether sealed or open reaction vessels were used and must document the manufacturer and model of the reactor, the method of monitoring the reaction mixture temperature, and the temperature-time profile. Reporting a wattage rating or power setting is not an acceptable alternative to providing temperature data. Manuscripts describing work done with domestic (kitchen) microwave ovens will not be accepted except for studies where the unit is used for heating reaction mixtures at atmospheric pressure.

3. Compound characterization

The Journal upholds a high standard for compound characterization to ensure that substances being added to the chemical literature have been correctly identified and can be synthesized in known yield and purity by the reported preparation and isolation methods. For all new compounds, evidence adequate to establish both identity and degree of purity (homogeneity) must be provided.

Identity
Melting point. All homogeneous solid products (e.g. not mixtures of isomers) should be charac­terized by melting or decomposition points. The colors and morphologies of the products should also be noted.
Specific rotations. Specific rotations based on the equation [α]^t_D = (100 α) / (l c) should be reported as unitless numbers as in the following example: [α]²⁰_D = -25.4 (c 1.93, CHCl₃), where c / g mL^-1 is concentration and l / dm is path length. The units of the specific rotation, (deg mL) / (g dm), are implicit and are not included with the reported value.
Spectra/Spectral Data. Important IR adsorptions should be given.
For all new diamagnetic substances, NMR data should be reported (¹H, ¹³C, and relevant heteronuclei). ¹H NMR chemical shifts should be given with two digits after the decimal point. Include the number of protons represented by the signal, signal multiplicity, and coupling constants as needed (J italicized, reported with up to one digit after the decimal). The number of bonds through which the coupling is operative, ^xJ, may be specified by the author if known with a high degree of certainty. ¹³C NMR signal shifts should be rounded to the nearest 0.01 ppm unless greater precision is needed to distinguish closely spaced signals. Field strength should be noted for each spectrum, not as a comment in the general experimental section. Hydrogen multiplicity (C, CH, CH₂, CH₃) information obtained from routine DEPT spectra should be included. If detailed signal assignments are made, the type of NOESY or COSY methods used to establish atom connectivity and spatial relationships should be identified in the Supporting Information. Copies of spectra should also be included where structure assignments of complex molecules depend heavily on NMR interpretation. Numbering system used for assignments of signals should be given in the Supporting Information with corresponding general structural formula of named derivative.
HPLC/LCMS can be substituted for biochemistry papers where the main focus is not on compound synthesis.

HRMS/elemental analysis. To support the molecular formula assignment, HRMS data accurate within 5 ppm, or combustion elemental analysis [carbon and hydrogen (and nitrogen, if present)] data accurate within 0.5 %, should be reported for new compounds. HRMS data should be given in format as is usually given for combustion analysis: calculated mass for given formula following with observed mass: (+)ESI-HRMS m/z: [molecular formula + H]⁺ calculated mass, observed mass. Example: (+)ESI-HRMS m/z: calculated for [C₁₃H₈BrCl₂N + H⁺] 327.92899, observed 327.92792.

NOTE: in certain cases, a crystal structure may be an acceptable substitute for HRMS/elemental analysis.

Biomacromolecules. The structures of biomacromolecules may be established by providing evidence about sequence and mass. Sequences may be inferred from the experimental order of amino acid, saccharide, or nucleotide coupling, from known sequences of templates in enzyme-mediated syntheses, or through standard sequencing techniques. Typically, a sequence will be accompanied by MS data that establish the molecular weight.

Example: Product was isolated upon column chromatography [dry flash (SiO₂, eluent EA, EA/MeOH gradient 95/5 → 9/1, EA/MeOH/NH₃ gradient 18/0.5/0.5 → 9/1/1, and flash chromatography (Biotage SP1, RP column, eluent MeOH/H₂O gradient 75/25 → 95/5, N-H column, eluent EA/Hex gradient 6/3 → EA). was obtained after flash column chromatography (Biotage SP NH column, eluent hexane/EA 4:6 → 2:6). Yield 968.4 mg (95 %). Colorless foam softens at 96-101 °C. [α]²⁰_D = +0,163 (c = 2.0×10^-3 g/mL, CH₂Cl₂).

HPLC purity: method A: RT 1.994, area 99.12 %; method C: RT 9.936, area 98.20 %.

Purity
Evidence for documenting compound purity should include one or more of the following:
(1) Well-resolved high field 1D ¹H NMR spectrum showing at most only trace peaks not attributable to the assigned structure and a standard 1D proton-decoupled ¹³C NMR spectrum. Copies of the spectra should be included as figures in the Supporting Information.
(2) Quantitative gas chromatographic analytical data for distilled or vacuum-transferred samples, or quantitative HPLC analytical data for materials isolated by column chromatography or separation from a solid support. HPLC analyses should be performed in two diverse systems. The stationary phase, solvents (HPLC), detector type, and percentage of total chromatogram integration should be reported; a copy of the chromatograms may be included as a figure in the Supporting Information.
(3) Electrophoretic analytical data obtained under conditions that permit observing impurities present at the 5 % level.
HRMS data may be used to support a molecular formula assignment but cannot be used as a criterion of purity.

4. Biological Data
Quantitative biological data are required for all tested compounds. Biological test methods must be referenced or described in sufficient detail to permit the experiments to be repeated by others. Detailed descriptions of biological methods should be placed in the experimental section. Standard compounds or established drugs should be tested in the same system for comparison. Data may be presented as numerical expressions or in graphical form; biological data for extensive series of compounds should be presented in tabular form. Tables consisting primarily of negative data will not usually be accepted; however, for purposes of documentation they may be submitted as supporting information.
Active compounds obtained from combinatorial syntheses should be resynthesized and retested to verify that the biology conforms to the initial observation.
Statistical limits (statistical significance) for the biological data are usually required. If statistical limits cannot be provided, the number of determinations and some indication of the variability and reliability of the results should be given. Referen­ces to statistical methods of calculation should be included. Doses and concentrations should be expressed as molar quanti­ties (e.g., mol/kg, μmol/kg, M, mM). The routes of administration of test compounds and vehicles used should be indica­ted, and any salt forms used (hydrochlorides, sulfates, etc.) should be noted. The physical state of the compound dosed (crystalline, amorphous; solution, suspension) and the formulation for dosing (micronized, jet-milled, nanoparticles) should be indicated. For those compounds found to be inactive, the highest concentration (in vitro) or dose level (in vivo) tested should be indicated.

Deposition of crystallographic data

Prior to submission, the crystallographic data included in a manuscript presenting such data should be deposited (together with associated structure factors) at the appropriate database. Crystallographic data associated with organic, metal-organic and inorganic structures should be deposited at the Cambridge Crystallographic Data Centre (CCDC) and FIZ Karlsruhe – Leibniz Institute for Information Infrastructure (FIZ Karlsruhe) joint deposition and access services at https://www.ccdc.cam.ac.uk/deposit. A deposition number will then be provided, which should be added to the reference section of the manuscript.

Authors are required to validate their CIF and structure factors using the checkCIF service developed by the International Union of Crystallography (IUCr) at https://checkcif.iucr.org/. Validation alerts returned by checkCIF should be resolved where possible before proceeding. A PDF output of the checkCIF report should be attached to the submission to help the referees reviewing the manuscript.

The RESULTS AND DISCUSSION should include concisely presented results and there significance discussed and compared to relevant literature data. The results and discussion may be combined or kept separate.

The inclusion of a CONCLUSION section, which briefly summarizes the principal conclusions, is highly recommended.

NOMENCLATURE is optional but, if the authors wish, a list of employed symbols may be included.

REFERENCES (35 maximum for the Original scientific papers, Short communications and Notes) should be numbered sequentially as they appear in the text. Please note that any reference numbers appearing in the Illustrations and/or Tables and corresponding captions must follow the numbering sequence of the paragraph in which they appear for the first time.

TIFF (Tagged Image File Format) is the recommended file format for bitmap, greyscale and colour images.

• Colour images should be in the RGB mode
• When supplying TIFF files, please ensure that the files are supplied at the correct resolution:

1. Line artwork: minimum of 1000 dpi
2. RGB image: minimum of 300 dpi
3. Greyscale image: minimum of 300 dpi
4. Combination artwork (line/greyscale/RGB): minimum of 500 dpi

• Images should be tightly cropped, without frame and any caption.
• If applicable please re-label artwork with a font supported by JSCS (Arial, Helvetica, Times, Symbol) and ensure it is of an appropriate font size.
• Save an image in TIFF format with LZW compression applied.
• It is recommended to remove Alpha channels before submitting TIFF files.
• It is recommended to flatten layers before submitting TIFF files.

Please be sure that quality of an image cannot be increased by changing the resolution from lower to higher, but only by rescanning or exporting the image with higher resolution, which can be set in usual "settings" facilities.

EPS
Virtually all common artwork creation software, such as Canvas, ChemDraw, CorelDraw, SigmaPlot, Origin Lab…, are capable of saving files in EPS format. This 'option' can normally be found under the 'Save As...' or 'Export...' commands in the 'File' menu.
For vector graphics, EPS (Encapsulated PostScript) files are the preferred format as long as they are provided in accordance with the following conditions:

• when they contain bitmap images, the bitmaps should be of good resolution (see instructions for TIFF files)
• when colour is involved, it should be encoded as RGB
• an 8-bit preview/header at a resolution of 72 dpi should always be included
• embed fonts should always included and only the following fonts should be used in artwork: Arial, Helvetica, Times, Symbol
• the vertical space between the parts of an illustration should be limited to the bare necessity for visual clarity
• no data should be present outside the actual illustration area
• line weights should range from 0.35 pt to 1.5 pt
• when using layers, they should be reduced to one layer before saving the image (Flatten Artwork)

JPEG
Virtually all common artwork and graphic creation software is capable of saving files in JPEG format. This 'option' can normally be found under 'the 'Save As...' or 'Export...' commands in the 'File' menu.
JPEG (Joint Photographic Experts Group) is the acceptable file format only for colour and greyscale photographs. JPEG can be created with respect to photo quality (low, medium, high; from 1 to 10), ensuring file sizes are kept to a minimum to aid easy file transfer. Images should have a minimum resolution of 300 dpi. Image width: minimum 3.0 cm; maximum 12.0 cm.

Please be sure that quality of an image cannot be increased by changing the resolution from lower to higher, but only by rescanning or exporting the image with higher resolution, which can be set in usual "settings" facilities.

SIZING OF ARTWORK
JSCS aspires to have a uniform look for all artwork contained in a single article. Hence, it is important to be aware of the style of the journal.
Figures should be submitted in black and white or, if required, colour (charged). If coloured figures or photographs are required, this must be stated in the cover letter and arrangements made for payment through the office of the Serbian Chemical Society.
As a general rule, the lettering on an artwork should have a finished, printed size of 11 pt for normal text and no smaller than 7 pt for subscript and superscript characters. Smaller lettering will yield a text that is barely legible. This is a rule-of-thumb rather than a strict rule. There are instances where other factors in the artwork, (for example, tints and shadings) dictate a finished size of perhaps 10 pt. Lines should be of at least 1 pt thickness.
When deciding on the size of a line art graphic, in addition to the lettering, there are several other factors to address. These all have a bearing on the reproducibility/readability of the final artwork. Tints and shadings have to be printable at the finished size. All relevant detail in the illustration, the graph symbols (squares, triangles, circles, etc.) and a key to the diagram (to explain the explanation of the graph symbols used) must be discernible.
The sizing of halftones (photographs, micrographs,...) normally causes more problems than line art. It is sometimes difficult to know what an author is trying to emphasize on a photograph, so you can help us by identifying the important parts of the image, perhaps by highlighting the relevant areas on a photocopy. The best advice that can be given to graphics suppliers is not to over-reduce halftones. Attention should also be paid to magnification factors or scale bars on the artwork and they should be compared with the details inside. If a set of artwork contains more than one halftone, again please ensure that there is consistency in size between similar diagrams.

General sizing of illustrations which can be used for the Journal of the Serbian Chemical Society:
Minimum fig. size: 30 mm width
Small fig. size - 60 mm width
Large fig. size - 90 mm width
Maximum fig. size - 120 mm width

Pixel requirements (width) per print size and resolution for bitmap images:

A: 300 dpi >   RGB or Greyscale image
B: 500 dpi >    Combination artwork (line/greyscale/RGB)
C: 1000 dpi> Line artwork

The designation of physical quantities and graphs formatting
The designation of physical quantities on figures must be in italic, whereas the units are in upright letters. They should be in Times New Roman font. In graphs a slash should be used to separate the designation of a physical quantity from the unit (example: p / kPa, j / mA cm^-1, T₀ / K, t / h, ln (j / mA cm^-2)…). Designations such as: p (kPa), t [min]…, are not acceptable. However, if the full name of a physical quantity is unavoiable, it should be given in upright letters and separated from the unit by a comma (example: Pressure, kPa, Temperature, K…). Please do not use the axes of graphs for additional explanations; these should be mentioned in the figure captions and/or the manuscript (example: "pressure at the inlet of the system, kPa" should be avoided). The axis name should follow the direction of the axis (the name of y‑axis should be rotated by 90°). Top and right axes should be avoided in diagrams, unless they are absolutely necessary. Decimal numbers must have decimal points and not commas in the axis labels in graphical presentations of results. Thousands are separated, if at all, by a comma and not a point.
