Magneticallyseparable Fe3O4 nanoparticles endow with an efficient and economic route for the synthesis of propargylamines by the three-component coupling of aldehyde, amine, and alkyne through C–H activation. The reaction is especially effective for reactions involving aliphatic aldehydes and no additional co-catalyst or activator is required. High catalytic activity and ease of recovery using an
磁性可分离的Fe 3 O 4纳米粒子通过醛类,胺类和炔烃通过C–H活化的三组分偶联,提供了一种高效而经济的合成炔丙胺的途径。该反应对于涉及脂族醛的反应特别有效,不需要额外的助催化剂或活化剂。高催化活性和使用外部磁场易于回收是该催化系统的其他环保特性。催化剂循环使用五次,而催化活性没有明显损失。
