It was found that the rhodium complexes are efficient catalysts for the hydrosilylation of olefins with triethoxysilane. Seven α olefins, decene, dodecene, allyl benzene,allyl phenyl ether, chloroundecene, methyl butyl acrylate, cyclohexene were usedas substrate to evaluate the catalytic activity and selectivity of the rhodium complexes. Terminal addition products were obtained from all olefins, More than 78 of dodecene, decene, allyl phenyl ether （10×10 -3 mol）were completely hydrosilylated with complex containing 4.9×10 -6 mol rhodium with in 1.5～1.8 h. 聚－γ－N（β－苯硫基）乙基胺丙基硅氧烷 聚－γ－N（β－丁硫基）乙基胺丙基硅氧烷 铑络合物 催化剂 氢化 硅氢化 poly γ N（ β phenylsulfidie）ethylamionoprophylsioxane poly γ N（ β butylsulfide）ethylaminopropylsiloxane rhodium complex catalyst Hydrogenation hydrosilylation O634.41;O643.36 1998-04-01 2021-04-01 4
