Methyldichlorosilane → Dichloro(3-phenylpropyl)silane

Participants

Reaction Steps

Reaction between styrene and methyldichlorosilane with platinum catalyst in the presence of sodium 1-octanesulfonate. 624 mg Styrene and 732 mg methyldichlorosilane were introduced into a glass tube, and 40 mg of sodium 1-octanesulfonate were added. 0.9 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 71% and a phenethylmethyldichlorosilane yield of 46%. The ratio between the phenethylmethyldichlorosilane and the (α-methylbenzyl)methyldichlorosilane was 18:1.
