Highly efficient O-silylation of alcohol with vinylsilane was developed using a catalyst system consisting of [(COE)(2)RhCl](2) and HCl. In this reaction, a key intermediate is chlorosilane, generated from vinylsilane and HCl, which can be regenerated in the catalytic cycle. Various alcohols and vinylsilanes were applied to the preparation of silyl ether compounds with this catalyst system.
