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
