Procedure

To a solution of 24.3 g of 2-nitrophenyl 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, 25.2 g of 2-nitrophenyl 2,3-dichloropropanesulfonate, B.P 167°-169°C/0.015 mmHg, was obtained in a yield of 80.3%.
