Procedure

Reaction between styrene and methyldichlorosilane with platinum catalyst in the presence of sodium dodecylsulfate. 427 mg Styrene and 498 mg methyldichlorosilane were introduced into a glass tube, and 55 mg of sodium dodecylsulfate was added. 1 mg Of a toluene solution of a 0-valent platinum complex of divinylsiloxane (0.4 wt % platinum content) was added. The tube was sealed and placed in a 100° C. oil bath where it was heated for 20 hours. After cooling, the tube contents were analyzed by gas chromatography revealing a styrene conversion of 45% and a phenethylmethyldichlorosilane yield of 20%. The ratio between the phenethylmethyldichlorosilane and the (α-methylbenzyl)methyldichlorosilane was 34:1.
