Abstract
A new acetylide-silylene complex, Cp(CO)2W(SiPh 2)(CCSiMe3) (4), was synthesized by the reaction of Cp(CO)2W(NCMe)Me with Ph2HSiC=CSiMe3. Complex 4 reacted with acetone to give the six-membered cyclic vinylidene complex Cp(CO)2W=C=C(SiMe3)CMe2OSiPh2 (5) by acetone insertion into the acetylide-silylene framework. Treatment of 5 with 4-(dimethylamino)pyridine resulted in the formation of the alkenylcarbyne complex Cp(CO)2W=CC(=CMe2)SiMe3 (8) and cyclic diphenylsiloxanes.
