Versuchsvorschrift

A sealed autoclave, charged with 288 parts of 2,5-diisopropylbenzenesulfonyl chloride, 5 parts of antimony pentachloride and 600 parts carbon tetrachloride and 36 parts chlorine, is shaken at 150° for 6 hr. The reaction solution is washed with sodium bisulfite and water. The washed solution is dried and the solvent distilled under reduced pressure. The crude residue can be recrystallized from a suitable solvent to give 3-chloro-2,5-diisopropylbenzenesulfonyl chloride.
