Title:

PROCESS FOR PRODUCING FLUOROSULFONYL FLUORIDE COMPOUND

Document Type and Number:

WIPO Patent Application WO/2002/044138

Kind Code:

A1

Abstract:

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 XSO¿2?R?A¿-E?1¿ (1) with R?B¿-E?2¿ (2) to obtain XSO¿2?R?A¿-E-R?B¿ (3), reacting the compound (3) with fluorine in a liquid phase to obtain FSO¿2?R?AF¿-E?F¿-R?BF¿ (4), and decomposing the compound (4) to obtain FSO¿2?R?AF¿-E?F1¿ (5). In the formulae, R?A¿ represents a divalent organic group; E?1¿ represents a monovalent reactive group; R?B¿ represents a monovalent organic group; E?2¿ represents a monovalent group reactive with E?1¿; E represents a divalent connecting group formed by the reaction of E?1¿ with E?2¿; R?AF¿ represents a divalent organic group formed by the fluorination of R?A¿, etc.; R?BF¿ represents the same group as R?B¿, etc.; E?F¿ represents a divalent connecting group formed by the fluorination of E, etc.; E?F1¿ represents a monovalent group formed by the decomposition of E?F¿; and X represents a halogen atom.
