N–H Bond Dissociation Enthalpies and Facile H Atom Transfers for Early Intermediates of Fe–N2 and Fe–CN Reductions
Fe-mediated biological nitrogen fixation is thought to proceed via either a sequence of
proton and electron transfer steps, concerted H atom transfer steps, or some combination
thereof. Regardless of the specifics and whether the intimate mechanism for N2-to-NH3
conversion involves a distal pathway, an alternating pathway, or some hybrid of these
limiting scenarios, Fe–N x H y intermediates are implicated that feature reactive N–H bonds.
Thermodynamic knowledge of the N–H bond strengths of such species is scant, and is …
