10-Fold Increase in Hydrogen Atom Transfer Reactivity for a Series of S = 1 FeIV=O Complexes Over the S = 2 [(TQA)FeIV=O]2+ Complex via Entropic Lowering of Reaction Barriers by Secondary Sphere Cycloalkyl Substitution

Nonheme iron enzymes utilize S = 2 iron(IV)-oxo intermediates as oxidants in biological oxygenations. In contrast, corresponding synthetic nonheme FeIV=O complexes characterized to date favor the S = 1 ground state that generally show much poorer oxidative reactivity than their S = 2 counterparts. However, one intriguing exception found by Nam a decade ago is
