摘要: 6-(ω'-十一碳烯氧甲基)-1-硫杂-4,7,1O,13-四氧杂环十五烷与三乙氧基硅烷进行硅氢加成,产物依次以气相法二氧化硅固载、氯亚铂酸钾或三氯化铑络合,合成了相应的二氧化硅-聚硅氧烷负载硫杂-15-冠-5-铂、铑配合物,并研究了它们在烯烃与三乙氧基硅烷的硅氢加成反应中的催化性能.结果表明,二者均为硅氢加成反应的高效催化剂.

关键词: 硫杂冠醚, 有机硅聚合物, 铂配合物, 铑配合物, 硅氢加成催化剂

Abstract: Silica-polysiloxane-supported thiacrown ether platinum, rhodium complexes were prepared from 6- (ω -undecenyloxymethyl)-1-thia-4, 7, 10, 13-tetraoxacyclopentadecane via hydrosilylation with trlethoxysilane.The products were immobilized on fumed silica, sequentially, followed by reacting with potassium chloroplatinite or rhodium chloride.The complexes exhibited high catalytic activities for the hydrosilylation of olefins with triethoxysilane.

Key words: Thiacrown ether, Organosilicon polymer, Platinum complex, Rhodium complex, Hydrosilylation catalyst
