In contrast to monohydrosilanes (R 3 SiH), which in the presence of supported gold nanoparticles primarily undergo typical β‐( E )‐hydrosilylation reactions with alkynes, dihydrosilanes (R 2 SiH 2 ) under catalysis of Au/TiO 2 lead to cis ‐1,2‐dehydrogenative disilylation reactions at room temperature with high selectivity. The disilyl adducts can be further functionalized through a one‐pot procedure, catalyzed by the same catalyst, to form substituted 2,5‐dihydro‐1,2,5‐oxadisiloles or 1,4‐disila‐2,5‐cyclohexadienes.
