Procedure

Reaction between styrene and dimethylchlorosilane with platinum catalyst in the presence of N-dimethylsilyl-N-methylacetamide. 526 mg Styrene and 408 mg dimethylchlorosilane were introduced into a glass tube, and 1 mg of N-dimethylsilyl-N-methylacetamide was 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 then 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 4.8% and a phenethyldimethylchlorosilane yield of 4.4%. The ratio between the phenethyldimethylchlorosilane and (α-methylbenzyl)dimethylchlorosilane was 15:1.
