Abstract
According to the present invention, there is provided a production process of a 2-fluoroacrylic ester including: a bromination step of converting a 2-fluoropropionic ester to a 2-bromo-2-fluoropropionic ester by reaction of the 2-fluoropropionic ester with a nitrogen-bromine bond-containing brominating agent in the presence of a radical initiator; and a dehydrobromination step of reacting the 2-bromo-2-fluoropropionic ester with a base. It is not necessary in this process to adopt very-low-temperature conditions and to use a stoichiometric amount of expensive reagent. The target 2-fluoroacrylic ester can be thus produced at low cost.
