Title:
METHOD FOR PRODUCING α-CHLOROACRYLIC ACID ESTER
Document Type and Number:
WIPO Patent Application WO/2024/053502
Kind Code:
A1
Abstract:
The present invention provides: a method for producing an α-chloroacrylic acid ester with excellent productivity or the like; and the like. The present invention discloses a method for producing a compound that is represented by formula (2), the method comprising a step A in which a compound that is represented by formula (1) is reacted with chlorine in the presence of a polar solvent. (In the formulae, each of R1 and R2 independently represents a hydrogen atom or an organic group, or alternatively, the R1 and R2 moieties combine with each other to form a ring together with an adjacent carbon atom; and R3 represents an alkyl group which may have one or more substituents, an aryl group which may have one or more substituents, or an aralkyl group which may have one or more substituents.)
