Participants

Reaction Steps

Octyltoluene (50 g.-0.245 mole) as prepared in Table 1 was added slowly at 5°-10° C. with stirring over one half hour (some exotherm) to 81 g. (0.69 mole) chlorosulfonic acid in a 250 ml. round bottom flask fitted with air stirrer, thermometer, addition funnel, reflux condenser, scrubber and ice bath. The reaction mixture was allowed to stir for three hours at 25°-30° C. and then stand overnight. It was poured onto 900 g. ice, 500 ml. diethyl ether was added and the mixture was stirred until the ice melted. The resulting organic phase was washed with water, 30% aqueous Na2CO3, again with water, dried over Na2SO4 and the solvent was evaporated. Thirty nine g. of octylmethylbenzenesulfonyl chloride was obtained.
