Biomimetic catalytic method produces phenoxazinone and phenazine derivatives from o-aminophenols, indicating air as a viable oxidant.
A biomimetic iron-porphyrin catalyst with a imidazole axial ligand has been developed to catalyze oxidative condensation of o -aminophenols and o -phenylenediamines to synthesize phenoxazinone and phenazine derivatives using air as oxidant.
