A novel method for the synthesis of 1-silyl-substituted 1,3-butadienes, based on [RuHCl(CO)(PCy3)2]-catalyzed silylative coupling of terminal (E)-1,3-dienes with vinylsilanes, is reported. The reaction provides a facile and straightforward access to (E,E)-dienylsilanes in a highlystereoselective fashion (especially for aryl-substituted dienes) and opens a valuable and general synthetic route for the
