SYNTHESIS AND CATALYTIC ACTIVITY OF POLYSILSES- QUIOXANE-SUPPORTED S-S-N TRIDENTATE LIGAND PLATINUM COMPLEX

N,N-双(β-甲硫乙基)γ-(三乙氧硅基)丙胺用气相法二氧化硅固载,再与氯亚铂酸钾作用,合成了三齿型铂配合物-聚γ-[N,N-双(β-甲硫乙基)胺基]丙基倍半硅氧烷铂配合物.研究了该配合物对烯烃与三乙氧基硅烷的硅氢加成反应的催化特性.

A novel type polymer-bound tridentate 2S-N ligand platinum complex, fumed silica-poly-γ-bis-N, N-(β-methylmercaptoethyl) amino propyl silsesquioxane platinum complex, has been synthesized from N, N-bis (β-methylmercaptoethyl) y-(triethoxysilyl) propylamine by hydrolysis of the monomer or cohydrolysis of it with dodecyltriethoxysilane and immobilization on fumed silica, followed by reacting with ponssium chloroplatinite in acetone under Ar atmosphere. It was found that they are efficient catalysts for the hydrosilylation of olefins with triethoxysilane. The influences of the nature of substrate, reaction temperature, the amount of complex used on the catalytic activity, as well as the recovery and reused property of them were investigated.
