PROCESS FOR PRODUCTION OF FLUORINATED SULFONYL FLUORIDES

The present invention provides a process for producing a fluorinated sulfonyl fluoride useful as e.g. a material for an ion exchange resin, and a novel chemical substance useful as an intermediate in the production process. That is, to provide a process comprising oxidizing Y-S-RA-E-RB by means of an oxidizing agent essentially containing a halogen atom to obtain XSO2-RA-E-RB, and in a case that X is a fluorine atom, reacting the compound with fluorine in a liquid phase as it is, and in a case that X is a halogen atom other than a fluorine atom, converting X into a fluorine atom, and then reacting the obtained compound with fluorine in a liquid phase to obtain FSO2-RAF-EF-RBF, and then decomposing it to obtain FSO2-RAF-COF (wherein RA is a bivalent organic group such as an alkylene group, RB is a monovalent organic group such as a perfluoroalkyl group, E is -CH2OCO-, Y is a monovalent organic group such as a cyano group or the like, X is a halogen atom, RAF is a bivalent organic group having RA fluorinated or the like, RBF is the same group as RB or the like, and EF is -CF2OCO-).
