The synthesis of trans-PtCl2(L-Se)2 (I; L = 10-selenabenzo-15-crown-5-)is described, and its possible structure is suggested. The influence factors including the nature of substrate, the reaction temperature, the amount of complex used and the chem. atomsphere on its catalytic activity for the hydrosilylation of olefins by HSi(OEt)3 were investigated. I is an efficient catalyst for the hydrosilylation; in a certain case the turnover no. is >62,000.
