Spectroscopic Evidence for Acid-Catalyzed Disproportionation Reaction of Oxoiron(IV) Porphyrin to Oxoiron(IV) Porphyrin π-Cation Radical and Iron(III) Porphyrin

The disproportionation reaction of oxoiron(IV) porphyrin complex (II) to oxoiron(IV) porphyrin π-cation radical complex (I) and iron(III) porphyrin complex (III) have been proposed in various react...
