Title: METHOD FOR PRODUCING FLUORINATED COMPOUND
Abstract:
The present invention addresses the problem of providing a novel method for producing a compound having a fluoromethylene group with high efficiency. The problem can be solved by a method for producing a compound represented by formula (1) [wherein R1 represents an organic group; RX represents a hydrogen atom or a fluorine atom; R2a, R2b, R2c and R2d may be the same as or different from one another and independently represent -Y-R21 or -N(-R22)2, or R2b and R2c may be lined to each other to form a bond; Y represents a bond, an oxygen atom or a sulfur atom; R21 represents a hydrogen atom or an organic group; and R22's may be the same as or different from each other in every event, and independently represent a hydrogen atom or an organic group], a ring-closed or ring-opened derivative of the compound, said method comprising step A of reacting a compound represented by formula (2) [wherein X represents a leaving group; and other symbols are as defined above] with a compound represented by formula (3) [wherein the symbols are as defined above] in the presence of a reducing agent under the irradiation with light.
