実験手順

A solution of 10.6 ml of phenylcyclohexane in 100 ml of methylene chloride was added at 5° C. within 30 minutes to 13.8 ml of chlorosulfonic acid. The mixture was stirred at 5° C. for 1 hour, poured into 400 ml of a 20% ammonium chloride solution and extracted twice with 300 ml of methylene chloride each time. The organic phases were combined, dried with magnesium sulphate and the solvent was removed on a rotary evaporator. 13.6 g of 4-cyclohexyl-benzenesulfonyl chloride separated as a reddish oil, which was used without further purification.
