Title: Oxidation of Naphthalene with a Manganese(IV) Bis(hydroxo) Complex in the Presence of Acid [Naphthalene Oxidation of Manganese(IV)-Bis(Hydroxo) Complex in the Presence of Acid]

Naphthalene oxidation with metal–oxygen intermediates is a difficult reaction in environmental and biological chemistry. Herein, we report that a Mn IV bis(hydroxo) complex, which was fully characterized by various physicochemical methods, such as ESI–MS, UV/Vis, and EPR analysis, X–ray diffraction, and XAS, can be employed for the oxidation of naphthalene in the presence of acid to afford 1,4–naphthoquinone. Redox titration of the Mn IV bis(hydroxo) complex gave a one–electron reduction potential of 1.09 V, which is the most positive potential for all reported nonheme Mn IV bis(hydroxo) species as well as Mn IV oxo analogues. Here, kinetic studies, including kinetic isotope effect analysis, suggest that the naphthalene oxidation occurs through a rate–determining electron transfer process.
