Abstract

(Chemical Equation Presented) Position determines properties: The oxidative properties of [FeIV(O)(L)(X)] species (L = tetradentate N4 ligand, X = monodentate ligand) depend on the position of the X ligand. The Fe=O unit is a poorer oxidant with an electron-donating cis ligand but becomes a much better oxidant when this ligand is trans to the oxo group. This difference in reactivity reflects perturbations to the electronic structure of the highly covalent Fe=O moiety.
