In the presence of Pd(0) and a phosphine, hydrosilylation of 1,3-enynes with Me2SiHCl proceeds to yield dienylsilanes with the silicon function added to the internal alkyne carbon atom and with (E)-configuration of newly formed olefinic bond. The silanols isolated after hydrolysis of the primarily obtained products serve as precursors to conjugated dienes with different substitution patterns.
在Pd(0)和磷化氢的存在下,1,3-烯炔与Me 2 SiHCl的硅氢加成反应会生成二烯基硅烷,其硅官能团添加到内部炔烃碳原子上,并且新形成的烯键具有(E)-构型。最初获得的产物水解后分离出的硅烷醇用作具有不同取代方式的共轭二烯的前体。
