A solution of 25.2 g (0.150 mole) of phenyl vinyl sulfone in 100 ml of carbon tetrachloride and 30 ml of glacial acetic acid was treated with 30.1 g (0.150 mole) of p-t-butylbenzenesulfenyl chloride. There was an exotherm of 2° within 10 minutes. The red color of the sulfenyl chloride disappeared within 24 hours. Evaporation of the solvent left 54 g (98%) of crude product m.p. 58°-69°. Recrystallization from 100 ml of ethyl acetate-petroleum ether (1:1) gave 29 g (52%) of colorless crystals, m.p. 67°-69°.
