Trifluoroacetic acid → Phenethyltriethoxysilane

Participants

Reaction Conditions

Reaction Steps

208 mg Of styrene, 328 mg of triethoxysilane, and 52 mg of toluene were placed in a glass reaction tube and 0.005 ml of trifluoroacetic acid was added. Then, 0.002 ml of a toluene solution of a 0-valent platinum complex of divinyltetramethyldisiloxane (platinum content: 0.4 Wt. %) was added to this mixture. The reaction tube was sealed with Teflon tape and heated for 1 hour in an oil bath at 50° C. When the tube contents were analyzed by GC-MS following cooling, the conversion rate of styrene was 41.4% and phenethyltriethoxysilane was produced at a yield of 30.5%. The yield of (α-methylbenzyl)triethoxysilane was 1.2%.
