Abstract
An object of the present invention is to provide, for example, a novel method for synthesizing a fluorovinyl ether compound from a fluorine-containing vinyl compound. This problem is solved by a method for producing a compound represented by formula (1): wherein Ra1 is a hydrogen atom, a halogeno group, an alkyl group, a fluoroalkyl group, or an aromatic group optionally having one or more substituents, Rf is a fluoro group or a perfluoroalkyl group, Ra2 is a hydrogen atom, a halogeno group, an alkyl group, a fluoroalkyl group, or an aromatic group optionally having one or more substituents, or (i) Ra1 and Ra2, (ii) Ra1 and Rf, or (iii) Rf and Ra2 may be linked to each other, Rb1 is Rs, Rb2 is a hydrogen atom or Rs, Rb3 is a hydrogen atom or Rs, or two or three of Rb1, Rb2, and Rb3, taken together with the adjacent carbon atom, may form a ring optionally having one or more substituents, and Rs, in each occurrence, is the same or different and represents a hydrocarbon group optionally having one or more substituents, the method comprising step A of reacting a compound represented by formula (2): wherein Rx is a leaving group, and other symbols are as defined above, wit…
