Abstract
The title ruthenium complex was found to catalyze the hydrosilylation and/or dimerization of phenylacetylene in the presence of a variety of hydrosilanes. Chlorohydrosilanes (HSiMeCl2, HSiMe2Cl and HSiCl3) favored the formation of the corresponding β-silylstyrenes while HSiEt3 favored the formation of 1,4-diphenylbuteneyne; Z-isomers were the major product regardless of the substituents on silicon.
