expeditious and solvent‐free synthesis of propargylamines via A3‐coupling of aldehydes, alkynes, and amines has been proposed. A wide range of aldehydes, alkynes and amine substrates undergo A3‐coupling to produce propargylamines in good to excellent yields with good functional tolerance, such as that towards alkoxy, hydroxy, C‐X (X = F, Cl, Br) as well as amide and C=C bonds. Furthermore, the catalyst could
已经提出了通过醛,炔烃和胺的A 3偶联,异质的Pd-Cu NWs催化快速无溶剂合成炔丙基胺。各种醛,炔烃和胺底物经过A 3偶联生成炔丙基胺,收率好至极佳,且具有良好的功能耐受性,例如对烷氧基,羟基,C-X(X = F,Cl,Br)作为酰胺和C = C键 此外,该催化剂可以容易地回收并且可以重复使用至少5个循环而不会显示出明显的催化活性损失。
