FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing fluorine-containing perhalogenated benzenes containing in molecule at least one fluorine atom, of general formula (I), where n = 1-5, m = 6-n. Method involves reaction of halogen-containing benzenes containing in a molecule at least one fluorine atom, of general formula (I), where m = 0-4, n = 1-5, m + n ≤ 5, with N-chloramide in a medium of a strong acid at temperature not exceeding boiling point of any of components of mixture.
EFFECT: method enables to obtain a highly pure product with high output.
