摘要

本文报道二氧化硅负载的三苯膦铂络合物——聚γ-(m-二苯膦苯基)丙基硅氧烷铂络合物对三甲氧基硅烷与不饱和化合物进行硅氢加成反应的催化特性.在底物用量的万分之一摩尔量的铂络合物存在下

1-己烯、1-癸烯、1-十二碳烯、苯基烯丙醚和ω-氯代十一碳烯在60或40℃平稳地与三甲氧基硅烷发生硅氢加成反应

唯一地得到末端加成产物

产率均在85％以上.其催化活性在反应初期低于四(三苯膦)合铂

但后期反应速度和硅氢化产率均较高.实验表明

聚γ-(m-二苯膦苯基)丙基硅氧烷与四(三苯膦)合铂反应制得的铂络合物(1)比与氯铂酸反应制得的铂络合物(Ⅱ)催化活性高.其次

反应气氛对硅氢加成反应具有决定性的影响.在空气气氛中

硅氢化反应平稳地进行;在氮气气氛中

不发生反应.

Abstract

Catalytic characteristics of poly-γ-(m-diphenylphosphinophenyl) propylsiloxane platinum complex

a silicone-supported triphenylphosphine-platinum complex

for the hydrosilylation of olefins with trimethoxysilane was reported in this work. The hydrosilylation reaction was carried out at 40 or 60℃ under air atmosphere in the presence of the title complex as catalyst. Terminal addition products were obtained

and the yields of them were above 85% in all cases. The catalytic activity of the title complex was higher than that of its homogeneous co-unterpart

tetrakis (triphenylphosphine) platinum complex. No reaction took place when ni-trogen was used as reaction atmosphere.
