Reaction Conditions

Reaction Steps

A solution of 2,4-dichloro-5-methylthiobenzoyl chloride (25 g.; 0.097 mole) in chloroform (1.30 ml.) is cooled in ice water to 20° C. and irradiated with a 200 watt bulb while a slow stream of chlorine is bubbled into the reaction mixture for four hours. The reaction mixture is stirred at 25° C. for 18 hours; then the solvent is removed by distillation at reduced pressure. The 2,4-dichloro-5-trichloromethylthiobenzoyl chloride which remains (14.0 g.; 40%) melts at 79°-81° C. after recrystallization from hexane.
