O-2-adduct complex of meso-tetrakis(alpha,alpha,alpha,alpha-o-pivalamidophenyl)porphinatoiron( II) with an intramolecularly coordinated proximal histidine
meso-Tetrakis(alpha,alpha,alpha,alpha -o-pivalamidophenyl iron(II) with an intramolecularly coordinated proximal histidine forms a stable O-2-adduct complex in benzene solution at 25 degreesC; the O-2-binding affinity (P-1/2: 1.7 Torr) is significantly low compared to that of the N-alkylimidazole bound analogue.
