Abstract
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. wherein Ris a bivalent organic group such as a fluoroalkylene group, Ris a group having Rfluorinated, or the same group as R, each of Rto Rwhich are independent of one another, is a hydrogen atom, etc., each of Rto Ris a fluorine atom, etc., Ris a monovalent organic group, Ris a group having Rfluorinated, or the same group as R, E is a bivalent connecting group, Eis the same group as E, or a group having E fluorinated, Eis a group formed by scission of E, each of Xto Xis a hydrogen atom, etc., and each of Xto Xis a fluorine atom, etc.
