Procedure

224 mg Of octene-1, 329 mg of triethoxysilane and 400 mg of toluene were placed in a glass reaction tube and 0.004 ml of acetic acid was then added to the tube. Then, 0.001 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 30 minutes in an oil bath at 50° C. When the contents were analyzed by GC-MS following cooling, the conversion rate of the octene-1 was 96% and n-octyltriethoxysilane was produced at a yield of 89%.
