Reactivity of the isolated catecholatoiron complex with O2 and the spectroscopic observation of the reversible catecholate ligand exchange reveal that a stable chelated catecholate species may be activated to be reactive with O2 in the catalytic system.

Selective extradiol oxygenation of 3,5-di-tert-butylcatechol 1 with O2 catalysed by Fe2+ is achieved in THF in the presence of water; the different selectivity obtained by FeCl2 and FeCl3 in THF-H2O and THF-pyridine supports the explanation of the intra- and extra-diol oxygenations by Fe3+ and Fe2+, respectively, as proposed in the enzymatic systems.

In a biomimetic transformation, the selective oxidation of catechol (2) to Z,Z-muconic acid (3) has been achieved under extremely mild conditions using methyl(trifluoromethyl)dioxirane (1b). Both dioxirane 1b and dimethyldioxirane (1a) have been applied to the oxidation of 2,6-di-tert-butylphenol (4); the product natures suggest the incursion of radical pathways.
