Fluorolactone and method for producing same

Abstract

The present disclosure provides, for example, a method that can produce a fluorolactone compound from hexafluoropropylene oxide or the like in a single step. The present disclosure relates to a method for producing a compound represented by formula (1): wherein two R1 are the same and each is a fluorine atom or a fluoroalkyl group, the method comprising step A of reacting a compound represented by formula (2): wherein R1 is as defined above, with a compound represented by formula (3): wherein R31, R32, and R33 are the same or different and each is a hydrogen atom or an alkyl group, or two of them are optionally linked to each other to form a ring optionally having one or more substituents, and a compound represented by formula (4-1) or the like: wherein R41, R42, R43, and R44 are the same or different and each is a hydrogen atom ox an alkyl group, or two of them are optionally linked to each other to form a ring optionally having one or more substituents.
