(μ-1,2-Peroxo)diiron(III) complexes (2-R) with dinucleating ligands (R-L) generated from the reaction of bis(μ-hydroxo)diiron(II) complexes [Fe2(R-L)(OH)2]2+ (1-R) with dioxygen in acetone at −20 °C provide a diiron-centred electrophilic oxidant, presumably diiron(IV)-oxo species, which is involved in aromatic ligand hydroxylation.
