Serb. Chem. Soc. VL - 82 IS - 11 SE - Organic Chemistry DO - 10.2298/JSC161221081S UR - https://shd-pub.org.rs/index.php/JSCS/article/view/4394 SP - 1211-1221 AB - <p>This study was an attempt to prepare copper nanoparticles and to determine their catalytic activity employing walnut shell (WS) residue as a green support and a reusable material. The nanocatalyst was characterized though inductively coupled plasma optical emission spectrometry (ICP-OES), N<sub>2</sub>-sorp­tion analysis, X-ray powder diffraction (XRD), energy-dispersive X-ray spec­troscopy (EDS), and transmission electron microscopy (TEM). The catalytic performance of CuNPs@WS was then studied in the preparation of propargyl­amines <em>via</em> a three-component reaction. The catalyst could be recovered and reused without a significant decrease in its activity over eight reaction cycles. The simple methodology described herein is an economic, ecofriendly and practical method accompanied by higher yields.</p> ER -
