摘要
4-氧杂-6,7-双甲硫基三甲氧基硅烷用气相法二氧化硅固载,再与氯亚铂酸钾作用,合成了双齿型硫醚铂络合物——聚-4-氧杂-6,7-双甲硫基庚基硅氧烷铂络合物。它对烷氧基硅烷与烯烃的硅氢加成反应具有良好的催化活性和突出的回收再用性能。其结构通过元素分析和XPS进行了表征。
A new type polymer-supported bidentate sulfide ligands platinum complex, fumed silica-bound poly(4-oxa-6,7-dimethyl-mercaptoheptyl) siloxane platinum complex, has been synthesized starting from 2,3-dimethylmercaptopropyl allylether via hydrosilylation by trimethoxysilane followed by hydrolysis and immobilization with water and fumed silica, then reacting with potassium chloroplatinite in acetone. It exhibited good catalytic activity for the hydrosilylation of olefins by trialkoxysilane, and could be reused several times without loss of its activity. Its structure was characterized by elemental analysis and XPS, and a possible structure pattern has been suggested.
