Abstract
The invention concerns a method for the synthesis of chlorinated aniline on the ring and comprising at least a sp3 hybridization carbon atom both perhalogenated and bearing a fluorine atom. Said method is characterized in that it comprises a step which consists in chlorinating a precursor aniline of said chlorinated aniline, said chlorination being carried out in a hydrofluoric medium capable of exchanging chlorine and fluorine in benzyl position. The invention is useful for the synthesis of organofluorinated and/or chlorinated compounds.
