WebSelective Photo-Induced Oxidation with O 2 of a Non-Heme Iron(III) Complex to a Bis(imine-pyridyl)iron (II) Complex Non-heme iron(II) complexes of pentadentate N4Py (N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine) type ligands undergo visible light-driven oxidation to their iron(III) state in the presence of O 2 without ligand degradation. WebIn this regard, we demonstrate that monitoring the Soret and Q-band regions of high-valent iron-oxo (ferryl heme) intermediates in horseradish peroxidase (HRP) is well suited to detect ultratrace amounts of H 2 O 2 impurities in alcohols in the range of 0.001–1000 μM using UV/Vis spectrophotometry.
