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 R a1 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, R a2 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) R a1 and R a2 , (ii) R a1 and Rf, or (iii) Rf and R a2 may be linked to each other, R b1 is R s , R b2 is a hydrogen atom or R s , R b3 is a hydrogen atom or R s , or two or three of R b1 , R b2 , and R b3 , taken together with the adjacent carbon atom, may form a ring optionally having one or more substituents, and R s , 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 R x is a leaving group, and other symbols are as defined above, with a compound represented by formula (3): wherein the symbols in the formula are as defined above, in the presence of a transition metal catalyst.
