title: Unexpected kinetic complexity in the formation of a nonheme oxoiron(IV) complex.
abstract: The stoichiometric formation of [FeIV(O)(TPA)(NCMe)]2+ (TPA = tris(2-pyridylmethyl)amine) from the reaction of [FeII(TPA)(NCMe)2]2+ with 1 equiv. peracetic acid exhibits more kinetic complexity than might be expected from the simple stoichiometry. A multiple-pathway mechanism with an FeIV-peracetic acid species, [(TPA)FeIV(O)((H)O3CR)]2+/+, as the primary oxidant is proposed.
