The present invention addresses the problem of providing a new method for producing a compound including a fluoromethylene group. The problem is accomplished by a method for producing a compound represented by formula (1) (wherein R1 is an organic group, RA is a hydrogen atom or a fluorine atom, R4a is a hydrogen atom or an organic group, R4b is a hydrogen atom or an organic group, R5 a is a hydrogen atom or an organic group, R5b is a hydrogen atom or an organic group, and R2 is a hydrogen atom or an organic group, and wherein R2 may have been linked to R4a to form a ring), the method comprising step A in which a compound represented by formula (2) (wherein X1 is a leaving group and the other symbols are the same as defined above) is reacted with a compound represented by formula (3) (wherein X2 is a leaving group and the other symbols are the same as defined above) optionally in the presence of a reducing agent with light irradiation. |
