摘要: 4,7-二硫杂壬基三甲氧基硅烷以气相法二氧化硅固载化,再与氯亚铂酸钾反应,合成了气相法二氧化硅固载的聚-4,7-二硫杂壬基倍半硅氧烷铂配合物。该配合物用量为烯烃摩尔数十万分之一时,仍能有效地催化烯烃与三乙氧基硅烷的硅氢加成反应,单程烯烃转化数可达80000。
关键词: 负载型催化剂, 双齿型硫铂配合物, 硅氢化, 聚硫杂硅氧烷
Abstract: Fume silica-bound poly-4,7-dithianonylsesquisiloxane platinum complex was prepared from 4,7-dithianonyltrimethoxysilane and fume silica via hydrolysis, followed by treatment with potassium chloroplatinite in acetone under Ar atmosphere. The complex exhibited a high catalytic actvity on the hydrosilylation of olefins with triethoxysilane. Even at a molar ratio of olefin to complex of 105, the hydrosilylation reaction took place smoothly with the turnover number more than 80000.
Key words: supported catalyst, bidentate sulfide-platinum complex, hydrosilylation, polythiasiloxane
