The invention discloses a method for preparing 1,2-dicarbonyl compound by photocatalytic oxidation reaction, comprising the following steps: mixing an unsaturated triple bond compound, a coordination catalyst and a solvent to obtain a solution A; A is illuminated to obtain a 1,2-dicarbonyl compound. The reaction of the invention can be realized by light irradiation in an oxygen-containing environment, the whole process is simple and efficient, and the reaction conditions are very mild; no traditional iridium and ruthenium complexes are used as coordination catalysts, the amount of catalyst used is small, and the catalytic system is simple and efficient; The reaction can be scaled up to the gram scale, reflecting the potential application of this catalytic process in organic reactions and industrial production. |
