Abstract
An improved process for hydrosilating alkynes with hydridosilane in the presence of a platinum catalyst selected from a group consisting of platinum halides and reaction product of platinum halides with organosilicon compounds having terminal aliphatic unsaturation. The process uses a cycloalkadiene comprising about six to 20 carbon atoms as a catalyst modifier to reduce formation of the bis-silated adduct of the alkynes.
