The role of oxygen in the mechanism of the intramolecular photoredox reaction of FeIII protoporphyrin IX in alkaline aqueous ethanol
Abstract
The evidence of superoxide formation during the irradiation of FeIII protoporphyrin IX in oxygenated alkaline aqueous ethanol and the very short re-oxidation time of the photoredox FeII porphyrin product are consistent with a photoinduced electron transfer from ethanol to oxygen occurring with the assistance of an FeIII porphyrin ethanolate complex.
