Abstract
An object of the present invention is to provide a process for producing α-fluoroacrylic acid esters at a high starting material conversion and a high yield. The present invention provides, as a means to achieve the object, a process for producing a compound represented by formula (1):wherein R1 and R2 are the same or different and each represent alkyl, fluoroalkyl, aryl optionally substituted with at least one substituent, halogen, or hydrogen; and R3 represents alkyl, fluoroalkyl, or aryl optionally substituted with at least one substituent, the process comprising step A of reacting a compound represented by formula (2):wherein the symbols are as defined above, with carbon monoxide and an alcohol represented by formula (3):R3—OH (3)wherein the symbol is as defined above, in the presence of a transition metal complex catalyst containing at least one bidentate phosphine ligand and a base to thereby obtain the compound represented by formula (1).
