aminomethylamination of allenes with aminals by CN bond activation is described. This direct and operationally simple method provides a fundamentally novel approach for the synthesis of 1,3‐diamines. Mechanistic studies suggest that a unique cationic π‐allylpalladium complex containing an aminomethyl moiety is generated as a key intermediate through the carbopalladation of the allene with a cyclometalated
与被C缩醛胺丙二烯的一种新的和原子的经济钯催化aminomethylamination N键激活进行说明。这种直接且操作简单的方法为1,3-二胺的合成提供了一种根本上新颖的方法。机理研究表明,独特的包含氨基甲基部分的阳离子π-烯丙基铝配合物是通过环烷基化钯-烷基物质进行烯丙基碳键合反应而生成的,是作为关键中间体的关键中间体。
