An efficient catalytic system for the alkylation of amines with either alcohols or amines under mild conditions has been developed, using cyclometallated iridium complexes as catalysts. The method has broad substrate scope, allowing for the synthesis of a diverse range of secondary and tertiary amines with good to excellent yields. By controlling the ratio of substrates, both mono‐ and bis‐alkylated
使用环金属化铱配合物作为催化剂,已经开发出一种在温和条件下将胺与醇或胺烷基化的有效催化体系。该方法具有广泛的底物范围,允许以良好或优异的产率合成多种范围的仲胺和叔胺。通过控制底物的比例,可以高选择性获得单烷基化胺和双烷基化胺。特别是,甲醇可用作烷基化试剂,选择性地提供N-甲基化产物。对于该反应观察到强溶剂作用。
