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
