Styrene → Phenethyltriethoxysilane

Participants

Reaction Steps

Reaction between styrene and triethoxysilane with platinum catalyst in the presence of bis(2-ethylhexyl) hydrogenphosphate (C4H9CH(C2H5)CH2O)2P(═O)OH). 0.334 g Styrene and 0.540 g triethoxysilane were introduced into a glass tube, and 3 mg of bis(2-ethylhexyl) hydrogenphosphate were added using a microsyringe. 0.8 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 septum and placed in a 100° C. oil bath where it was heated for 1 hour. After cooling, the tube contents were analyzed by gas chromatography revealing a styrene conversion of about 29% and a phenethyl triethoxysilane yield of 16%. The ratio between the phenethyl triethoxysilane and the (α-methylbenzyl)triethoxysilane was 5.8:1.
