Procedure

224 mg Of octene-1, 328 mg of triethoxysilane and 56 mg of toluene were placed in a glass reaction tube and 8 mg of benzoic acid added. Then, 0.001 ml of an isopropyl alcohol solution of chloroplatinic acid (platinum content: 0.39%) 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 contents were analyzed by GC-MS following cooling, the conversion rate of octene-1 was 97.5% and n-octyltriethoxysilane was produced at a yield of 91%.
