実験手順: About 468 grams (4.5 moles) of styrene and about 0.5 grams of di-t-butyl-p-cresol were charged to a one liter, three necked round bottom flask fitted with a magnetic stirrer, thermometer, dropping funnel and reflux condenser bearing a nitrogen by-pass on the vent. While stirring the flask contents were heated to 90° C, and a sufficient amount of about a 2% solution of chloroplatinic acid catalyst dissolved in dimethylether of ethylene glycok to give about 25 parts by weight of plantinum per million parts by weight of reactants was added. Then about 610 grams (4.5 moles) of trichlorosilane were slowly and continuously added via the dropping funnel over a one and one-half hour period while maintaining the reaction temperature at 90°-95° C. A vapor phase chromatogram on the reaction contents indicated there was an essentially complete conversion to product. The crude silane reaction product was then refined by a one plate distillation at 0.1 mm. pressure to yield about 1015 grams (4.24 moles) of phenylethyltrichlorosilane product ##STR22## (94.5% conversion) which had a boiling point of about 63°-64° C./0.1 mm Hg. fitted with a magnetic stirrer reflux condenser to give about 25 parts by weight of plantinum per million parts by weight of reactants was added continuously added via the dropping funnel over a one and one-half hour period while maintaining the reaction temperature at 90°-95° C A vapor phase chromatogram on the reaction contents was then refined by a one plate distillation at 0.1 mm

実験手順: Reaction between styrene and trichlorosilane with platinum catalyst (no substance acting as auxiliary catalyst). 518 mg Styrene and 694 mg trichlorosilane were introduced into a glass tube, and 2.5 mg of a toluene solution of a 0-valent platinum complex of divinylsiloxane (0.04 wt % platinum content) were added. The tube was sealed with Teflon tape and a rubber septum and then placed in a 50° C. oil bath where it was heated for 30 minutes. After cooling, the tube contents were analyzed by gas chromatography revealing a styrene conversion of 93% and a phenethyltrichlorosilane yield of 39%. The ratio between the phenethyltrichlorosilane and the (α-methylbenzyl)trichlorosilane was 5.5:1. placed in a 50° C. was heated for 30 minutes After cooling

実験手順: Reaction between styrene and trichlorosilane with platinum catalyst in the presence of a trimethylsilyl ester of methanesulfonic acid. 518 mg Styrene and 694 mg trichlorosilane were introduced into a glass tube, and 42 mg of a trimethylsilyl ester of methanesulfonic acid were added. 2.5 mg Of a toluene solution of a 0-valent platinum complex of divinylsiloxane (0.04 wt % platinum content) were added. The tube was sealed with Teflon tape and a rubber septum and placed in a 50° C. oil bath where it was heated for 30 minutes. After cooling, the tube contents were analyzed by gas chromatography revealing a styrene conversion of 11% and a phenethyltrichlorosilane yield of 8.7%. The ratio between the phenethyltrichlorosilane and the (α-methylbenzyl)trichlorosilane was 390:1. placed in a 50° C. was heated for 30 minutes After cooling
