Synopsis Nickel ( Ni(Sal CF3 ) ) and copper ( Cu(Sal CF3 ) ) complexes of an electron-deficient salen ligand were prepared, and their one-electron oxidized counterparts were studied using an array of experimental and theoretical methods. Ni(Sal CF3 ) undergoes ligand oxidation to afford a delocalized ligand radical, while Cu(Sal CF3 ) exhibits metal-based oxidation to aff...
