To a solution of 0.161 mole of m-nitrobenzenesulfenyl chloride in enough carbon tetrachloride to make 265 ml was added 34.1 g (0.160 mole) of m-nitrophenyl vinyl sulfone. The reaction mixture was allowed to stand at room temperature in a closed flask for several weeks. Evaporation of the solvent under reduced pressure gave 44 g (68%) of crude product m.p. 98°-110°. Recrystallization from 120 ml of toluene gave 23 g (36%) of pure product, m.p. 105.0°-106.5°.
