PROCESSES FOR PRODUCING A FLUOROSULFONYL GROUP-CONTAINING COMPOUND AND A COMPOUND LED FROM THE FLUOROSULFONYL GROUP-CONTAINING COMPOUND

摘要

A fluorosulfonyl group-containing compound having a high polymerization reactivity, a process for its production, a sulfonyl group-containing polymerizable monomer led from the sulfonyl group-containing compound, and a polymer obtainable by polymerizing the sulfonyl group-containing polymerizable monomer, are provided. A compound (3) is fluorinated to form a compound (4), and then, the compound (4) is subjected to a decomposition reaction to produce a compound (5). A preferred compound (5-1) of the compound (5) is thermally decomposed to produce a compound (7-1) having a high polymerization reactivity. (see formula 3) (see formula 4) (see formula 5) (see formula 5-1) (see formula 7-1) wherein R A is a bivalent organic group such as a fluoroalkylene group, R AF is a group having R A fluorinated, or the same group as R A, each of R B to R D which are independent of one another, is a hydrogen atom, etc., each of R BF to R DF is a fluorine atom, etc. , R E is a monovalent organic group, R EF is a group having R E fluorinated, or the same group as R E, E is a bivalent connecting group, E F is the same group as E, or a group having E fluorinated, E F1 is a group formed by scission of E F, each of X1 to X3 is a hydrogen atom, etc., and each of X1F to X3F is a fluorine atom, etc.
