Catalytic Two-Electron Reduction of O2 via MCET and PCET

MCET from Me2Fc to O2 in the presence of HCIO4 in benzonitrile (PhCN) or MeCN at 298 K is slow, as described above (eqn (6) and (7)), whereas MCET from CoTPP to O2 occurs rapidly (eqn (11) and (12)). These ean be combined 

The observed g value (2.0032) of the singly oxidized cobalt corrole, obtained by the chemical oxidation of (F5PhMes2Cor)Co with one equivalent of
