FIELD: chemistry.
SUBSTANCE: invention concerns method of obtaining compounds containing hydrofluoromethylenesulfonyl radical, involving: a) stage of R-S-M mercaptide condensation in solvent, where R is tertiary alkyl or benzyl, M is alkaline metal, with compound containing carbon atom in sp3 hybridisation, carrying hydrogen, fluorine, heavy halogen selected out of chlorine, bromine and iodine, and electron-acceptor group selected out of fluorine or Rf; b) stage of oxidation of compound obtained at stage a) by halogenation, preferably chlorination or bromination, in the presence of aqueous phase. Particularly the invention allows obtaining difluoromethanesulfinic or difluoromethanesulfonic acid derivatives.
EFFECT: eliminated need to use instable or expensive solvents with complex application method.
