title: The nature of heme-aniline interactions during hemin-mediated oxygen activation and insertion reactions.
abstract: The interaction of aniline with hemin during oxygen activation and insertion mediated by the metalloporphyrin has been studied by a combined theoretical, semiempirical, and experimental approach. Results indicate that association is via a planar pi bonding interaction between the aromatic pi electrons of the amine and tetrapyrrole ring system. The effect of very high concentrations of hydroxyl radical scavengers on the system is discussed.
