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 R.sup.1 represents an organic group, R.sup.X represents hydrogen or fluorine, R.sup.2a, R.sup.2b, R.sup.2c, and R.sup.2d are the same or different, and each represents YR.sup.21 or N(R.sup.22).sub.2, or R.sup.2b and R.sup.2c may join together to form a bond, wherein Y represents a bond, oxygen, or sulfur, R.sup.21 represents hydrogen or an organic group, and R.sup.22, 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.
