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 R
2
and R
2
are the same or different and each represent alkyl, fluoroalkyl, aryl optionally substituted with at least one substituent, halogen, or hydrogen; and
R
3
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):
R
3
—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).
