Selective Catalytic Hydrosilylation of Ethylene. Preparation of Ethyltrimethoxysilane by H2O Promoted RuCl3 ⋅ 3H2O Catalyst

The work describes an efficient one-step solvent-free synthesis of ethyltrimethoxysilane through hydrosilylation reaction catalyzed by RuCl3 ⋅ 3H2O–H2O. The procedure involves time point and dose of adding additive water. Excellent yields, short reaction times, and easy reaction handling under solvent-free and mild conditions are the most important advantages of the present protocol. A possible reaction mechanism was discussed by empirical method.
