Ethanol → Dichloro(3-phenylpropyl)silane

Participants

Reaction Steps

Reaction between styrene and methyldichlorosilane with platinum catalyst in the presence of N,N′-bis(trimethylsilyl)urea. 0.481 g Styrene and 0.549 g methyldichlorosilane were introduced into a glass tube, and an ethanol solution containing 0.124 mg N,N′-bis(trimethylsilyl)urea (6.2 wt %) was added with a microsyringe. 1 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 septum and then placed in a 100° C. oil bath where it was heated for 20 minutes. After cooling, the tube contents were analyzed by gas chromatography revealing a styrene conversion of 89% and a phenethylmethyldichlorosilane yield of 84%. The ratio between the phenethylmethyldichlorosilane and the (α-methylbenzyl)methyldichlorosilane was 21:1.
