Title:
METHOD FOR PRODUCING FLUORINE-CONTAINING SULFONAMIDE COMPOUND
Document Type and Number:
Japanese Patent JP2022141492
Kind Code:
A
Abstract:
To provide a method for producing a fluorine-containing sulfonamide compound used as raw material for a sulfonamide group-containing monomer, in short steps and at high yield, and a method for producing a sulfonamide group-containing monomer from the fluorine-containing sulfonamide compound obtained by the production method.SOLUTION: A method causes, for example, a polyfluoro oxygen-containing cyclic sulfone compound, represented by the upper formula below, to react with a diethyl amine into a sulfonamide compound, represented by the lower formula below, and then causes the reaction product to further react with a metal amide compound to de-HF the -CHF-CF3 site, thereby synthesizing a sulfonamide group-containing monomer.SELECTED DRAWING: None
