Worth their weight in gold : Au/CeO 2 nanoparticles are a highly active catalyst for the hydrosilylation of a large variety of unsaturated compounds with high chemo‐ and regioselectivity. To understand the nature of the catalytic active sites, Au I and Au III phosphine‐free stable organogold complexes and their supported counterparts were prepared and their relative activity towards hydrosilylation was elucidated.
