The latter is chlorinated in the side chains under free-radical conditions to give 2,4-dichloro-5-fluoro-3-dichloromethyl-1-trichloromethylbenzene. The latter is hydrolysed via 2,4-dichloro-5-fluoro-3-dichloromethylbenzoic acid, which can be isolated if necessary, to give 2,4-dichloro-5-fluoro-3-formyl-benzoic acid, the aldehyde group of which is reacted to give 2,4-dichloro-5-fluoro-3-N-hydroxyiminomethyl-benzoic acid, from which, with simultaneous conversion of the carboxyl group into the chlorocarbonyl group, water is eliminated using an acid chloride to give the nitrile 2,4-dichloro-3-cyano-5-fluoro-benzoyl chloride.
随后,在游离基条件下进行侧链的氯化,得到2,4-二氯-5-氟-3-二氯甲基-1-三氯甲基苯、后者被水解,经过2,4-二氯-5-氟-3-二氯甲基苯甲酸(如果需要此化合物可以分离),得到2,4-二氯-5-氟-3-甲酰苯甲酸,将其醛基反应,得到2,4-二氯-5-氟-3-N-羟基亚氨基甲基苯甲酸,用酰氯从其中除去水,同时将羧基转化为碳酰氯,得到一种腈,即2,4-二氯-3-氰基-5-氯-苯甲酰氯。
