An efficient synthetic route to alkenylsilnaes involving hydrosilylation of allenes by supported palladium-gold alloy catalysts has been developed. The catalytic activity and the product selectivity were drastically changed by the incorporation of palladium atoms into gold nanoparticles (NPs). The supported Pd-Au alloy catalysts with a low Pd/Au ratio were highly effective for the hydrosilylation at ambient temperature, in which the corresponding β-vinylsilanes were obtained in good to high yields with high selectivity.
