Novel copper nanoparticles supported on starch micro particles (CuNPs@MS) were prepared successfully and characterized by SEM, EDX, TEM, SAED, TGA, XPS, and XRD analyses. The easily synthesized and thermally stable CuNPs@MS have been applied as a green, degradable, and eco-friendly catalyst in a three component reaction of amines, aldehydes and alkynes for the preparation of diverse propargylamines
成功制备了负载在淀粉微粒上的新型铜纳米颗粒(CuNPs @ MS),并通过SEM,EDX,TEM,SAED,TGA,XPS和XRD分析对其进行了表征。易于合成且热稳定的CuNPs @ MS已被用作一种绿色,可降解且环保的催化剂,用于胺,醛和炔烃的三组分反应中,以制备各种炔丙基胺。反应在非均相条件下进行,催化剂成功地循环使用了五次,但活性有所降低。
