A novel oxidation catalyst comprising a mononuclear metal complex as an active ingredient is provided. A mononuclear metal complex represented by the general formula (1) is used as an active ingredient. In the general formula (I), R 1 , R 2 , R 3 , and R 4 are each independently selected from a hydrogen atom and a hydrocarbon group having 1 to 3 carbon atoms, and M is It is a metal atom that forms a planar four-coordinate coordination structure, and X is a halogen atom.
