首次合成了巯甲基化交联聚苯乙烯－铂络合物，将其用于催化不同结构的碳碳不饱和化合物与甲基二氯硅烷的加成反应，结果表明，该催化剂对乙炔、苯乙烯、苯乙炔、三烷基乙烯基硅烷等化合物具有很高的催化活性，对丙烯酸丁酯的催化活性显著降低，对甲基丙烯酸甲酯则无催化活性，该催化剂用于苯乙烯的硅氢加成反应，可重复使用２０次，而且回收再用非常方便． For the first time, mercaptomethylated cross-linked polystyrene-platinum complexes were synthesized and used to catalyze the addition reaction of carbon-carbon unsaturated compounds of different structures with methyldichlorosilane. The results showed that the catalysts were effective for the synthesis of acetylene, Styrene, phenylacetylene, trialkyl vinyl silane and other compounds with high catalytic activity of butyl acrylate significantly reduced the catalytic activity of methyl methacrylate is no catalytic activity of the catalyst for styrene, silicon Hydrogenation reaction can be reused 20 times, and recycling is very convenient.
