Silylstyrenes were prepared by the hydrosilylation reaction of acetylene with alkysilane using palladium(II) nitrate catalyst in the presence of various sulfides as ligands in toluene. The selectivity of product catalyzed by palladium complex was found to be higher than that catalyzed by previously reported Lewis acid. The effect of the ligands on the yield has been investigated. Sulfides containing less basic substituents increase the yield of product.
