通过Cp*（CO）2 W（NCMe）Me与Ph 2 HSiCSiMe 3反应，合成了一种新的乙炔基-硅烯配合物Cp*（CO）2 W（SiPh 2）（CCSiMe 3）（4）。配合物4与丙酮反应，通过丙酮插入乙炔基-硅烯基骨架，得到六元环亚乙烯基配合物Cp*（CO）2 W <$C <$C（SiMe 3）CMe 2 OSiPh 2（5）.用4-二甲氨基吡啶处理5，生成烯基碳炔配合物Cp*（CO）2 W * CC（CH 2CMe 2）SiMe 3（8）和环状二苯基硅氧烷。
A new acetylide−silylene complex, Cp*(CO)2W(SiPh2)(CCSiMe3) (4), was synthesized by the reaction of Cp*(CO)2W(NCMe)Me with Ph2HSiCCSiMe3. Complex4reacted with acetone to give the six-membered cyclic vinylidene complex Cp*(CO)2WCC(SiMe3)CMe2OSiPh2(5) by acetone insertion into the acetylide−silylene framework. Treatment of5with 4-(dimethylamino)pyridine resulted in the formation of the alkenylcarbyne complex Cp*(CO)2WCC(CMe2)SiMe3(8) and cyclic diphenylsiloxanes.
