Methyldichlorosilane → Dichloro(3-phenylpropyl)silane

Participants

Reaction Steps

Reaction between styrene and methyldichlorosilane with platinum catalyst in the presence of trimethylsilyl ester of methanesulfonic acid. 624 mg Styrene and 732 mg methyldichlorosilane were introduced into a glass tube, and 51 mg of a trimethylsilyl ester of methanesulfonic acid was added with a microsyringe. 0.9 mg Of a toluene solution of a 0-valent platinum complex of divinylsiloxane (0.04 wt % platinum content) was 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 95% and a phenethylmethyldichlorosilane yield of 71%. The ratio between the phenethylmethyldichlorosilane and the (α-methylbenzyl)methyldichlorosilane was 4.6:1.
