| 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. |
