A solution of 26.8 g (0.147 mole) of p-tolyl vinyl sulfone in 50 ml of carbon tetrachloride was treated with 32.8 g (0.146 mole) of p-bromobenzenesulfenyl chloride. There was an exotherm from 25° to 29° in one hour. The mixture was allowed to stand 72 hours. The solvent was removed at reduced pressure and the residue recrystallized from ethyl acetate-petroleum ether (1:1) to give colorless needles, m.p. 82.5°-84.0°.
