Abstract: The protonated and unprotonated N,N'-ethylene-bissalicylamidatoiron (III) ions, Fe (SALMH)2+ and Fe(SALM)+, undergo fast complexation with L-ascorbic acid to form ternary complexes, [Fe(SALM)(HASc)], and [Fe(SALM)(ASc)]- in which the ascorbate ion is chelated to FeIII centre. These ternary complexes further undergo intramolecular electron transfer via innersphere mechanism in the stopped flow time scale producing FeII and dehydroascorbic acid; the order of reactivity is kFe(SALMH) > kFe(SALM)ˉ.
