Procedure

871 mg Of divinylbenzene and 4.35 g of triethoxysilane were placed in a glass reaction tube and 0.015 ml of a toluene solution of a 0-valent platinum complex of divinyltetramethyldisiloxane (platinum content: 0.2 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 divinylbenzene was 56%; bis (2-triethoxysilylethyl) benzene was produced at a yield of 2.8%, (1-triethoxysilylethyl) (2-triethoxysilylethyl) benzene was produced at a yield of 3.7%, and bis (1-triethoxysilylethyl) benzene was produced at a yield of 0.1%. No production of (triethoxysilyl) ethylstyrene was observed.
