4-Chlorophenyl phenyl ether → 4-(4-Chlorophenoxy)benzene-1-sulfonyl chloride

Participants

Reaction Steps

Chlorosulfonic acid (9.7 mL, 0.147 mole) was added dropwise to 4-chlorophenoxybenzene (12.6 mL, 73.4 mmole) at room temperature with stirring. When addition was complete, the mixture was stirred at room temperature for 1 hour and then poured into ice water. The solid was collected by filtration, dried in the air, and recrystallized from petroleum ether and ethyl acetate to give 4-(4-chlorophenoxy)benzenesulfonylohloride (7.43 grams, 33%).
