摘要：

(Chemical Equation Presented) Extremely similar electronic structures and Fe-O bonding characterize FeIV=O S = 1 heme and non-heme species as a result of a decoupling of the oxoiron unit from the porphyrin (Por) π system in the heme complex (see scheme). However, along the reaction coordinate towards an FeIII-OH product, the Por π system interacts with the iron d orbitals, thus resulting in different reactivities for heme and non-heme complexes. © 2005 Wiley-VCH Verlag GmbH & Co.
