Procedure

130 mg Of styrene and 217 mg of triethoxysilane were placed in a glass reaction tube and 0.0014 mg of lauric acid was added. Next, 0.01 ml of an isopropyl alcohol solution of chloroplatinic acid (platinum content: 0.02 Wt. %) was added to this mixture. The reaction tube was sealed with Teflon tape and heated for 30 minutes in an oil bath at 50° C. When the tube contents were analyzed by GC-MS following cooling, the conversion rate of styrene was 35% and phenethyltriethoxysilane was produced at a yield of 23%. The yield of (α-methylbenzyl)triethoxysilane was 0.4%.
