摘要：

An efficient synthetic route to alkenylsilanes involving the hydrosilylation of allenes with supported Pd-Au alloy catalysts has been developed. The incorporation of Pd atoms into Au nanoparticles remarkably enhanced the catalytic activity and product selectivity. Pd-Au alloy catalysts with a low Pd/Au ratio were highly effective for the hydrosilylation at an ambient temperature, and the corresponding beta-alkenylsilanes were obtained as a main product in good to high yields.
