- Zur Synthese von Halogenmethandisulfonylfluoriden
-
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

PROBLEM TO BE SOLVED: To provide a production method that can obtain an alkanedisulfonyl difluoride in a high yield while minimizing an influence on a production apparatus.SOLUTION: A method for producing an alkanedisulfonyl difluoride includes fluorinating an alkanedisulfonyl dichloride to produce the alkanedisulfonyl difluoride in which the alkanedisulfonyl dichloride is reacted with hydrogen fluoride in a solvent to form a hydrogen bond complex with hydrogen fluoride.
