A versatile three-componentcoupling of aldehydes, alkynes and amines has been developed, catalyzed by Ni 2+ -exchanged Y-zeolite, which acts as an environmentally benign, recyclable, efficient and heterogeneous catalyst. This three-component (A 3 ) coupling (reported for the first time to proceed under nickel catalysis) is carried out under solvent-free conditions, and the corresponding propargylamines
一种多功能的醛、炔和胺的三组分偶联已被开发出来,由 Ni 2+ 交换的 Y 沸石催化,它作为一种环境友好、可回收、高效和多相的催化剂。这种三组分(A 3 )偶联(首次报道在镍催化下进行)是在无溶剂条件下进行的,相应的炔丙胺以良好到极好的收率获得。
