Transfer Step

Hydride transfer from NADH analogues to a nonheme Mn(iv)–oxo complex, [(Bn-TPEN)MnIV(O)]2+, proceeds via a rate-determining electron transfer step with no deuterium kinetic isotope effect (KIE = 1.0 ± 0.1) and via charge-transfer complexes formed in the reactions of Mn(iv)–oxo and NADH analogues.
