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.
