DERIVES DES BIS(PERFLUOROSULFONYL)METHANES, LEUR PROCEDE DE PREPARATION, ET LEURS UTILISATIONS .

摘要

Bis(perfluorosulphonyl)methanes, process for preparing same and uses thereof. The compounds of the invention are based on the formula (1/nM)+[(RFSO2)2CY]<-> in which Y denotes an electron-attracting group chosen from -C=N and RZ groupings in which Z denotes a carbonyl grouping, a sulphonyl grouping or a phosphonyl grouping and R denotes an organic monovalent grouping, M denotes a metal having valency n or an organic group capable of existing in the cationic form, RF denotes a perfluoroalkyl or perfluoroaryl grouping. Said compounds are especially useful in the production of electrochemical devices.
