Reductive activation of O2 is achieved by using the [FeIII(F20TPP)Cl] porphyrin through electrochemical reduction of the [FeIII(F20TPP)(O2-)] superoxo complex. Formation of the [FeIII(F20TPP) (OO)]- peroxo species is monitored by using low-temperature electronic absorption spectroscopy, electron paramagnetic resonance, and cyclic voltammetry. Its subsequent protonation to yield the [FeIII(F20TPP) (OOH)] hydroperoxo intermediate is probed using low-temperature electronic absorption spectroscopy and electron paramagnetic resonance.
