Into a 500 ml. three-necked flask were charged 108 g. (0.78 mole) 1-phenyl-ethanethiol, 126 g. (0.78 mole) vinyltrichlorosilane and 1.2 g. (0.5 weight percent) azobisisobutyronitrile catalyst. The contents were heated and stirred for 6 hours at 80°-90°C. Fractional distillation of the reaction mixture gave the product fraction, Cl3SiCH2CH2SCH(CH3)C6H5, b.p. 110°/0.53 mm Hg. Vapor phase chromatographic analysis of the distilled product (120 g.) showed it contained a mixture of alpha and beta isomers. Yield of (1-phenylethylthio)ethyltrichlorosilane was 85 percent, based on ViSiCl3 reacted.
