(Chemical Equation Presented) One primary goal in biomimetic research is to understand mechanisms of dioxygen activation; structures of reactive intermediates; and reactivities of the intermediates involved in catalytic oxidation reactions by metalloenzymes; such as heme and nonheme iron oxygenases. In this communication; we have reported the first example of generating nonheme iron(III)-hydroperoxo and iron(IV)-oxo complexes by activating O2 with a biologically important electron donor; an NADH analogue; and an acid. The formation of iron(III)-hydroperoxo and iron(IV)-oxo complexes was found to depend on the supporting ligands. We have also demonstrated that high-spin nonheme iron(II) complexes with a low oxidation potential are able to bind and activate O2 to generate the iron-oxygen intermediates. © 2009 American Chemical Society;
