    摘要： 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.

    摘要： A production process of a fluorosulfuric acid aromatic-ring ester according to the present invention includes reaction of an aromatic-ring hydroxyl compound with sulfuryl fluoride (SO 2 F 2 ) in the presence of a tertiary amine except pyridine and methylpyridine. The sulfuryl fluoride, used as the reactant in the production process according to the present invention, is widely adapted as a fumigant and is easily available on a large scale. Further, the target compound can be obtained rapidly with a high yield under moderate reaction conditions in the production process according to the present invention. In this way, all of the prior art problems can be solved in the production process according to the present invention. The production process according to the present invention is thus particularly useful for industrial production of the fluorosulfuric acid aromatic-ring ester.
