<p>A process by which a fluorosulfonyl fluoride compound useful as, e.g., a material for ion-exchange membranes can be efficiently produced at low cost without structural limitations while eliminating difficulties in production. The process comprises reacting XSO2RA-E1 (1) with RB-E2 (2) to obtain XSO¿2?R?A-E-RB¿ (3), reacting the compound (3) with fluorine in a liquid phase to obtain FSO¿2?R?AF-EF-RBF¿ (4), and decomposing the compound (4) to obtain FSO¿2?R?AF-EF1¿ (5). In the formulae, RA represents a divalent organic group; E1 represents a monovalent reactive group; RB represents a monovalent organic group; E2 represents a monovalent group reactive with E1; E represents a divalent connecting group formed by the reaction of E?1 with E2; RAF¿ represents a divalent organic group formed by the fluorination of RA, etc.; RBF represents the same group as RB, etc.; EF represents a divalent connecting group formed by the fluorination of E, etc.; EF1 represents a monovalent group formed by the decomposition of EF; and X represents a halogen atom.</p> |
