本文报道了首例碲杂冠醚铂配合物:10-碲杂苯并-15-冠-5铂配合物的合成, 并研究了它对烯烃与三乙氧基硅烷的硅氢加成反应的催化特性.实验结果表明:其催化活性不如相应的硒杂冠醚铂配合物,但对某些烯烃,如苯基烯丙醚, 仍有较高的催化活性

The synthesis of the 1st telluracrown ether Pt complex: 10-tellurabenzo-15-crown-5-Pt, is described. The influences of the nature of olefins, reaction temperature, the amount of title complex used, reaction atomsphere and introducing Hg on its catalytic activity for the hydrosilylation of olefins by triethoxysilane were studied. Its catalytic hydrosilylation activity is lower than that of the corresponding selenacrown ether Pt complex, but toward certain olefins, such as Ph allyl ether, it still exhibits high catalytic activity.
