Method for producing triazine derivative and organic copper compound

The present invention provides a method for producing a triazine derivative, which is suitable for industrial production. A method for producing a triazine derivative according to the present invention comprises a process for obtaining a compound that has a triazine skeleton, into which a substituent derived from an organic copper compound is introduced, by means of a reaction that uses an organic copper compound represented by formula (1). (1): Cu-R1 (In formula (1), R1 represents a perfluoroaryl group in which a fluorine atom may be substituted, a perfluoroheteroaryl group in which a fluorine atom may be substituted, a perfluoroalkyl group in which a fluorine atom may be substituted, a perfluoroalkenyl group in which a fluorine atom may be substituted, or a perfluoroalkynyl group in which a fluorine atom may be substituted.).
