Formation of the syn isomer of [FeIV(Oanti)(TMC)(NCMe)]2+ in the reaction of Lewis acids with the side-on bound peroxo ligand in [FeIII2-O2)(TMC)]+

Abstract

We demonstrate that the reactions of [FeIII2-O2)(TMC)]+ (TMC = tetramethylcyclam) with Lewis acids (H+ and NO+) afford the recently described syn isomer of [FeIV(O)(TMC)(NCMe)]2+ (and not the anti isomer as had been tacitly assumed). This outcome is a logical consequence of the fact that the side-on peroxo ligand is bound to the syn face of the Fe(TMC) unit in the precursor.
