(Chemical Equation Presented) High five: H-abstraction reactivity by oxo iron(IV) complexes with a quintet ground state is greatly enhanced by exchange stabilization arising from the increased number of d-d exchange interactions near the transition state (see picture). It is postulated that nonheme enzymes evolved to make use of this fundamental mechanism in activation of strong C-H bonds.
