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): whereinRis 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,Ris a hydrogen atom, a halogeno group, an alkyl group, a fluoroalkyl group, or an aromatic group optionally having one or more substituents, or(i) Rand R, (ii) Rand Rf, or (iii) Rf and Rmay be linked to each other,Ris R,Ris a hydrogen atom or R,Ris a hydrogen atom or R, ortwo or three of R, R, and R, taken together with the adjacent carbon atom, may form a ring optionally having one or more substituents, andR, in each occurrence, is the same or different and represents a hydrocarbon group optionally having one or more substituents, the method comprisingstep A of reacting a compound represented by formula (2): whereinRis a leaving group, andother 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.
