Reaction Conditions

Reaction Steps

216.5 g of 3-chloro-2,4-difluoro-benzotrifluoride in 440 ml of methylene chloride are initially introduced into a stirred apparatus, and 150 g of AlCl3 are introduced in small portions. The reaction is slightly exothermic. When the addition has ended, the mixture is heated under reflux (42° C.) for 2 hours, cooled and poured onto 1 l of ice-water. After intensive thorough mixing, the mixture is filtered over a suction filter and the organic phase is then separated off. After drying, the methylene chloride phase is distilled. 231 g of 3-chloro-2,4-difluoro-benzotrichloride with a boiling range of 124-126° C./18 mbar are obtained.
