摘要：

以1-己烯和三乙氧基硅烷的硅氢加成为模型反应,研究了碳硅烷树形大分子-铂络合物对于不饱和化合物的硅氢加成反应的催化活性,考察了n(N)／n(Pt)比值、温度、树形大分子代数等对催化活性的影响。结果表明,随催化剂n(N)／n(Pt)比值的增大,催化活性逐步降低,活性高峰处于n(N)／n(Pt)值为2～4之间。硅氢加成产物以β-加成产物为主,具有良好的选择性。

Abstract:

Catalytic activity of carbosilane dendrimer-Platinum complexes in thehydrosilylation of unsaturated compounds was studied by using the reaction of 1-Hexene and HSi(OEt)₃ as a model reaction. The effect of the ratio of N to Pt,temperature and the generation of dendrimers on the catalytic activity was investigated. The results showed the catalytic activity descended gradually with an increase of the ratio of N to Pt and that the optimal ratio was between 2 and 4. The β-addition product is the main product of the hydrosilylation. The catalyst has favorable selectivity.

Key words: carbosilane dendrimer-platinum complexe; catalysis activity; hydrosilylation
