Plausible Mechanisms of the Fenton-Like Reactions, M = Fe(II) and Co(II), in the Presence of RCO₂^– Substrates: Are OH^• Radicals Formed in the Process?

Abstract

DFT calculations concerning the plausible mechanism of Fenton-like reactions catalyzed by Fe­(II) and Co­(II) cations in the presence of carboxylate ligands suggest that hydroxyl radicals are not formed in these reactions. This conclusion suggests that the commonly accepted mechanisms of Fenton-like reactions induced oxidative stress and advanced oxidation processes have to be reconsidered
