Procedure

To a solution of 11.9 g of phenyl 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, 22.4 g of phenyl 2,3-dichloropropanesulfonate, B.P. 120°-125°C/0.005 mmHg, was obtained in a yield of 83.3%.
