FIELD: organic synthesis. SUBSTANCE: polyfluoroaromatic compounds are prepared by heating corresponding halogenated aromatics with alkali metal fluorides in presence of catalyst, in particular N,N',N"-hexasubstituted guanidinium halide. Reaction is carried out in medium composed of products of partial fluorination of initial halogenated aromatics, while desired products are continuously withdrawn. EFFECT: increased yield of desired products. 3 cl, 10 ex
