FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing N6-di(perfluoroalkoxy)phosphoryl sydnone imines and can be used in chemical industry. Disclosed is a method of producing N6-di(perfluoroalkoxy)phosphoryl sydnone imines from the corresponding sydnone imine hydrochlorides, comprising reacting the corresponding sydnone imine hydrochloride with phosphorus oxychloride in chloroform, mixture is heated to a boiling point, after which a solution of triethylamine is slowly added thereto, after prolonged boiling, the reaction mass is cooled to room temperature, telomere alcohols of general formula H(CF2CF2)nCH2OH, where n = 3–4, are added at night with further extraction of end product in free form.
EFFECT: novel efficient method of producing N6-di(perfluoroalkoxy) phosphoryl sydnone imines with high output.
