Method for producing fluorovinyl ether compound

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
• Ra1 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 is selected from the group consisting of a halogeno group, a sulfonic acid ester group, a fluorosulfonyl group, a nitro group, or a cyano 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.
