Efficient Hydrosilylation Reaction of Olefins Catalyzed by a Dinuclear Ruthenium Complex

Under mild reaction conditions, the dinuclear ruthenium catalyst is used to achieve an anti-Markovnikov hydrosilylation reaction of olefins. Notably, the reaction is extremely selective and no alkenylsilanes, olefin reduction products, or isomerization products are detected in this reaction.

Dinuclear metal synergistic catalysis is presented as a strategy for the hydrosilylation of olefins. Both aliphatic and aromatic olefins smoothly undergo anti-Markovnikov hydrosilylation under mild reaction conditions to produce the corresponding organosilicon products in moderate-to-excellent yields (42–96%) with high selectivity. The formation of alkenylsilanes, olefin reduction products, and isomerization products is not observed. Synthetically valuable functional groups such as chloro atom, methoxycarbonyl, and ester are tolerated well under the current reaction conditions. Control experiments and mechanistic studies suggest a synergistic catalytic mechanism involving bimetallic cooperation.
