Role of Protons in Superoxide Reduction by a Superoxide Reductase Analogue [PDF]
Inorganic Chemistry, 2005 Superoxide reduction by thiolate-ligated [FeII(SMe2N4(tren))]+ (1) involves two proton-dependent steps and a single peroxide intermediate, [FeIII(SMe2N4(tren))(OOH)]+ (2). An external proton donor is required, ruling out mechanisms involving H+ or H-atom abstraction from the ligand N-H.
