摘要
本文通过双（２－羟基乙基）硫酸与１，２一双（２’－对甲苯磺酞氧基乙氧基）苯缩合闭环，得到１０－硫杂苯并－１５－冠－５，后者再与氯亚铂酸钾反应得到标题配合物；同时研究了该配合物对烯烃与三乙氧基硅烷的硅氢加成反应的催化特性，并与硒、碲的类似配合物进行了比较．结果表明，此配合物是烯烃硅氢化反应的高效催化剂．
hiabenzo-15-crown-5(L) was prepared by condensation of bis(2-hydroxyethyl)sulfide with 1, 2-bis (2'-tosyloxyethoxy ) benzene and its platinum complex was obtained by reacting (L) with potassium chloroplatinite. The influencing factors including the nature of substrate, the reaction temperature, the amount of the complex used and the chemical atmosphere on the catalytic activity of the complex for the hydrosilylation of olefins by triethoxysilane were investigated, and its catalytic activity was compared with those of analogous platinum complex of selena- or tellura-crownether. The experimental data indicated that the title complex possessed the highest catalytic activity and the catalytic activity decreased in the order of S, Se, Te: S>Se Te.
