A new convenient and effective method for the synthesis of unsymmetrical 1,1-bis(silyl)ethenes is described. The synthetic methodology involves selective silylative coupling cyclization of N-methyl-N-(dimethylvinylsilyl)-2-(dimethylvinylsilyloxy)ethanamine catalyzed by a ruthenium hydride complex and subsequent one-pot reaction of the cyclic bis(silyl)derivative with Grignard reagents followed by alcoholysis
描述了一种新的方便有效的不对称1,1-双(甲硅烷基)乙烯合成方法。该合成方法包括由氢化钌络合物催化的 N-甲基-N-(二甲基乙烯基甲硅烷基)-2-(二甲基乙烯基甲硅烷基氧基)乙胺的选择性甲硅烷基化偶联环化,以及随后环状双(甲硅烷基)衍生物与格氏试剂的一锅反应,然后是醇解。结果,以区域控制的方式以相当高的效率生产了在硅原子上含有不同取代基的各种1,1-双(甲硅烷基)乙烯。
