γ-巯丙基三甲氧基硅烷与β-氯乙基二甲胺盐酸盐在甲醇钠存在下缩合,得到4-硫杂-6-二甲胺基己基三甲氧基硅烷。后者以气相法二氧化硅固载,再与氯亚铂酸钾反应,合成了二氧化硅固载的聚-4-硫杂-6-二甲胺基己基硅氧烷-铂配合物。它是烯烃硅氢加成的有效催化剂。
γ-mercaptopropyltrimethoxysilane and β-chloroethyldimethylamine hydrochloride are condensed in the presence of sodium methoxide to give 4-thia-6-dimethylaminohexyltrimethoxysilane. The latter is supported on fumed silica and then reacted with potassium platinum platinum oxide to synthesize a silica-supported poly-4-thia-6-dimethylaminohexylsiloxane-platinum complex. It is an effective catalyst for hydrosilylation of olefins.
