This invention solves the problem of providing an efficient, new method for producing a fluoromethylene-containing compound. The problem can be solved by a method for producing a compound represented by formula (1) or a ring-closed or ring-opened derivative of the compound, wherein R1 represents an organic group, RX represents hydrogen or fluorine, R2a, R2b, R2c, and R2d are the same or different, and each represents -Y-R21 or - N(-R22)2, or R2b and R2c may join together to form a bond, wherein Y represents a bond, oxygen, or sulfur, R21 represents hydrogen or an organic group, and R22, in each occurrence, is the same or different and represents hydrogen or an organic group; the 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 light irradiation.
本发明要解决的问题是提供一种生产含
