To a solution of 29.8 g (0.146 mole) of p-chlorophenyl vinyl sulfone in 50 ml of carbon tetrachloride at 25° C. was added 32.8 g (0.146 mole) of p-bromobenzenesulfenyl chloride. There was an exotherm of 4° within 52 minutes. The reaction mixture was allowed to stand for three days. Solvent was removed by evaporation at reduced pressure. The residue was recrystallized from 60 ml of ethyl acetate-petroleum ether (1:1) to give colorless needles, m.p. 76°-78°.
