Abstract: The title complex was synthesized from N,N-bis(β-ethylmercaptoethyl)y-(triethoxysilyl) propylamine by hydrolysis of the monomer or cohydrolysis of it with dodecyltriethoxysilane or phenyl-propyltriethoxysilane and immobilized on fumed silica, respectively, followed by reacting with rhodium chloride under Ar atmosphere in acetone. They are efficient catalysts for the hydrosilylation of olefins by triethoxysilane. The turnover number was more than 100 000 in one run in individual case. The plausible structure pattern of the complex is suggested. The influences of the nature of substrate, reaction temperature, the amount of complex used on the catalytic activity, as well as their recovery and reused property were investigated.
