To provide a new oxidation catalyst using a mononuclear metal complex as an effective component, having catalyst function in oxidation reaction in which phenol is produced at least from benzene, and capable of reducing the production of benzoquinone compared to the production of phenol.
The mononuclear metal complex represented by general formula (1) is used as an effective component. In general formula (I), R1, R2 and R3 are each independently either one selected from a hydrogen atom and 1-3C hydrocarbon groups, and R4 may be a substitution group having 0-3C sulfo group at the terminal. M is a metal atom forming a planar tetracoordinate structure. One X of three Xs is a halogen atom or a counter ion, and the two remainders Xs are a solvent molecules.
