Reaction between styrene and dimethylchlorosilane with platinum catalyst in the presence of trimethylsilyl-N,N-dimethyl carbamate. 526 mg Styrene and 480 mg dimethylchlorosilane were introduced into a glass tube, and 41 mg of trimethylsilyl-N,N-dimethyl carbamate were added using a microsyringe. 0.65 mg Of a toluene solution of a 0-valent platinum complex of divinylsiloxane (0.4 wt % platinum content) was added. The tube was sealed with Teflon tape and a rubber septum 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 38% and a phenethyl dimethylchlorosilane yield of 8.4%. The ratio between the phenethyl dimethylchlorosilane and the (α-methylbenzene) dimethylchlorosilane was 44:1.
