A platinum(0) complex, bearing a 1,3-divinyl-1,1,3,3-tetramethyldisiloxane (DVTMS) and an isolable dialkylsilylene ligand; was successfully synthesized by the reaction between the dialkylsilylene and Karstedt's catalyst. The downfield-shifted Si-29 NMR resonance, the smaller (1)J(Si,Pt) value, and the longer Si-Pt distance in this complex relative to the corresponding parameters in related bis(phosphine)coordinated silylene-platinum complexes suggest weaker pi-back-donation from the Pt center to the silylene, which is, however, still significant when compared to related DVTMS-ligated Pt complexes bearing N-heterocyclic carbenes, N-heterocyclic two-coordinate silylenes, or base-stabilized three-coordinate silylenes. The title complex displays excellent catalytic activity in the hydrosilylation of terminal olefins that contain functional groups such as epoxide and amine moieties.
