Procedure

To a solution of 23.2 g of 4-chlorophenyl 2-propenesulfonate in 80 ml of chloroform was added 7.1 g of chlorine absorbed in 20 ml of chloroform dropwise with stirring below 0°C. After the addition, the mixture was stirred for two hours at room temperature. By distillation of the solvent and fractionation, 25.5 g of 4-chlorophenyl 2,3-dichloropropanesulfonate, B.P. 143°-145°C/0.015 mmHg, was obtained in a yield of 84.2%.
