The reaction of methanedisulfonyl fluoride (1) with an N-halogenosuccinimide leads to the hitherto unknown dihalogenomethanedisulfonyl fluorides (halogen = chlorine (2b), bromine (2c), iodine (2d)).The hitherto unknown monohalogenomethanedisulfonyl fluorides (halogen = chlorine (3b), bromine (3c), iodine (3d)) can be prepared by the treatment of potassium- (4) and silver-di(fluorosulfonyl)-methanide (5) with the chlorine, bromine and iodine.The related fluorine derivatives were obtained by the electrochemical fluorination of 1 in anhydrous HF.Besides the known difluoromethanedisulfonyl fluoride (2a), the hitherto unknown monofluoromethanedisulfonyl fluoride (3a) could be isolated as a byproduct. - Keywords: Synthesis; Halogenomethane disulfonyl fluorides; Electrochemical fluorination; N-Halogenosuccinimides; Methanedisulfonyl fluoride; NMR spectroscopy; IR spectroscopy; Mass spectrometry
