Propargylamines are synthesized via metal-free activation of the C–halogen bond of dihalomethanes and the C–H bond of terminal alkynes in a three-component coupling without catalyst or additional base and under mild reaction conditions. The dihalomethanes are used both as solvents as well as precursors for the methylene fragment (C1) in the final product. The scope of the reaction and the influence
炔丙基胺是通过无卤活化二卤
甲烷的C-卤键和末端
炔烃的C-H键以三组分偶联的方式合成的,无需催化剂或额外的碱,并且在温和的反应条件下进行。二卤
甲烷既用作溶剂,也用作最终产品中亚甲基片段(C 1)的前体。已经研究了反应范围和各种反应变量的影响。提出了一个合理的反应机理,并讨论了可能在该过程中原位产生的各种中间体的参与。不含
金属的条件也使该协议在环境上无害,并且原子经济。
