摘要

本文叙述了一种新型有机硅聚合物负载配位催化剂——聚-4

7-二硫杂壬基倍半硅氧烷铑配合物的合成、结构及其对烯烃硅氢化反应的催化性能.标题配合物在用量为烯烃摩尔量的十万分之一时仍具有良好的催化活性

烯烃的转化数达到80

000.

Abstract

In this paper

we described the synthesis

structure

catalytic behavior of a new type of polymer-bound coordinate catalyst

silica-bound poly 4

7-dithianonylsilsesquioxane rhodium complex. The complex exhibited good catalytic activity for the hydrosilylation reaction of olefins with trie-thoxysilane at 110 to 130℃. Even if the amount of complex used was lowered to the molar ratio of 10-5(rhodium to olefin)

the hydrosilylation reaction took place smoothly and the turnover number of olefin was more than 80

000 in such a case. The structure of the polymer ligand was discussed in detail

and the possible structure of coordinate center was sugested.
