A family of commercially available organolithium compounds were found to effectively catalyze the heterodehydrocoupling of silanes and amines under ambient conditions. Ubiquitous nBuLi (1) was utilized as the benchmark catalyst, where an array of primary, secondary, and tertiary arylsilanes were coupled to electron-donating amines, affording aminosilanes in high conversions with short reaction times
人们发现一系列市售有机锂化合物在环境条件下可有效催化硅烷和胺的杂脱氢偶联。使用普遍存在的正丁基锂 (1) 作为基准催化剂,其中一系列伯、仲和叔芳基硅烷与给电子胺偶联,以短反应时间提供高转化率的氨基硅烷。初步机理分析与涉及高价硅中间体形成的亲核型系统一致。这项工作强调了 Si-N 杂脱氢偶联的可及性,有机锂试剂成为这种转化中最简单且最具成本效益的预催化剂。
