Two different, highly oxidized iron complexes of N-methyltetra-p-tolylporphyrin (N-MeTTPH) have been detected by 1H and 2H NMR spectroscopy after oxidation with m-chloropcroxybenzoic acid. In CH2Cl2/CH3OH (4:1, v/v) in the presence of sodium methoxide (N-MeTTP)FeIICl is converted to (N-MeTTP)FeII(OCH3) and then to (CH3O)(N-MeTTP)FeIV = O upon addition of the peroxyacid. The latter is observable over the temperature range -90 to 0°C, has a magnetic susceptibility of 2.9 μB (S = 1 ), and is reduced by phenyldimethylphosphine to (N-MeTTP)FeII(OCH3). In the absence of sodium methoxide, (N-MeTTP)FeIICl is oxidized by the peroxyacid to form a very unstable species observable from -90 to -75°C whose 1H NMR spectrum shows large hyperfine shifts for the meso aryl substituents that are consistent with the presence of a π-N- methylporphyrin radical in the product.
