Highly efficient palladium catalyst system for addition of trihydrosilanes to acetylenes and its application to thermally stable polycarbosilane synthesis
Abstract
Regio- and stereo-selective mono-, di- and tri-alkenylation of trihydrosilanes with monoynes proceeded smoothly with a Pd–PCy3 catalyst, while the reaction of phenylsilane with 1,4-diethynylbenzene provided a thermally stable and blue light emissive polycarbosilane.
