first example of efficient reductive amination of ketones/aldehydes with amines using BH3N(C2H5)3 as a catalyst and a reductant under mild conditions, affording various tertiary and secondary amines in excellent yields. A mechanistic study indicates that BH3N(C2H5)3 plays a dual function role of promoting imine and iminium formation and serving as a reductant in reductive amination.
在此,我们报告了使用 BH 3 N(C 2 H 5 ) 3作为催化剂和还原剂在温和条件下用胺有效还原胺化酮/醛的第一个例子,以优异的产率提供各种叔胺和仲胺。机理研究表明,BH 3 N(C 2 H 5 ) 3具有促进亚胺和亚胺形成以及在还原胺化中作为还原剂的双重作用。
