Vinyl halides containing vinylic and allylic silane terminators undergo a stereospecific palladium(0)-catalyzed cross-coupling with derivatives of terminal propargylic and homopropargylic alcohols to polyunsaturated silanes. Basic stable and unstable protecting groups were tolerated under slightly different reaction conditions.
