摘要
将巯甲基化交联聚苯乙烯 -铂络合物微球用于催化苯乙烯与甲基二氯硅烷的加成反应 ,考察了用硅氢加成试剂处理催化剂的时间对其催化行为的影响。发现催化活性中心主要是Pt (Ⅱ ) ,催化剂的后处理时间明显影响硅氢加成反应的诱导期和活性 。
Microbead of thiolmethylene crosslinked polystyrene supported platinum complex was used to catalyze the hydrosilylation of styrene with dichloromethylsilane. The effects of the time treated catalyst with silanizing agent on catalytic properties were investigated.It was found that the real catalytic active center was Pt(Ⅱ), and the induction and activity of the hydrosilylation was significantly influenced by the post treatment time of the catalyst. The hydrosilylation mechanism catalyzed by this catalyst was suggested.
