摘要： 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.
