An oxoiron(IV) cation radical is generated upon two-electron oxidation of an iron(III) complex bearing an electron-rich methoxy substituted bTAML framework and thoroughly characterized via multiple spectroscopic techniques and density functional theory (DFT). Reactivity studies demonstrate faster rates for oxidation of strong aliphatic sp 3 C-H bonds than for its corresponding oxoiron(V) valence tautomer.
