Procedure

Reaction between styrene and trichlorosilane with platinum catalyst in the presence of a trimethylsilyl ester of methanesulfonic acid. 518 mg Styrene and 694 mg trichlorosilane were introduced into a glass tube, and 42 mg of a trimethylsilyl ester of methanesulfonic acid were added. 2.5 mg Of a toluene solution of a 0-valent platinum complex of divinylsiloxane (0.04 wt % platinum content) were added. The tube was sealed with Teflon tape and a rubber septum and placed in a 50° C. oil bath where it was heated for 30 minutes. After cooling, the tube contents were analyzed by gas chromatography revealing a styrene conversion of 11% and a phenethyltrichlorosilane yield of 8.7%. The ratio between the phenethyltrichlorosilane and the (α-methylbenzyl)trichlorosilane was 390:1.
