Title:
FLUOROLACTONE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/230822
Kind Code:
A1
Abstract:
The present disclosure provides a method with which a fluorolactone compound can be produced in a single step from hexafluoropropylene oxide or the like. The present disclosure relates to a method for producing a compound represented by a formula (1) [in the formula, the two R1 groups are the same and are each a fluorine atom or a fluoroalkyl group]. The method includes a step A for reacting a compound represented by a formula (2) [in the formula, the two R1 groups are defined in the same way as above], a compound represented by a formula (3) [in the formula, R31, R32 and R33 may be the same as, or different from, each other, and each denote a hydrogen atom or an alkyl group, or two of these may bond to each other to form a ring that may have one or more substituent groups], and a compound represented by a formula (4-1) [in the formula, R41, R42, R43 and R44 may be the same as, or different from, each other, and each denote a hydrogen atom or an alkyl group, or two of these may bond to each other to form a ring that may have one or more substituent groups].
