Direct evidence for an iron(IV)-oxo porphyrin pi-cation radical as an active oxidant in catalytic oxygenation reactions.
A high-valent iron(IV)-oxo porphyrin pi-cation radical is an active oxidant in the catalytic oxygenation of organic substrates by an iron(III) porphyrin complex and peracids, whereas an iron(III)-oxidant porphyrin adduct is a sluggish oxidant in iron porphyrin model reactions.
