Methyldichlorosilane → Dichloro(3-phenylpropyl)silane

Participants

Reaction Steps

Reaction between styrene and methyldichlorosilane with platinum catalyst in the presence of sodium cyclohexylsulfamate. 427 mg Styrene and 498 mg methyldichlorosilane were introduced into a glass tube, and 38 mg of sodium cyclohexylsulfamate were 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 50° C. oil bath where it was heated for 72 hours. After cooling, the tube contents were analyzed by gas chromatography revealing a styrene conversion of 85% and a phenethylmethyldichlorosilane yield of 70%. The ratio between the phenethylmethyldichlorosilane and the (α-methylbenzyl)methyldichlorosilane was 8.7:1.
