Catalytic and Stoichiometric Baeyer-Villiger Oxidation Mediated by Nonheme Peroxo-Diiron(III), Acylperoxo, and Iodosylbenzene Iron(III) Intermediates

In this paper we describe a detailed mechanistic studies on the [Fe-II(PBO)(2)(CF3SO3)(2)] (1), [Fe-II(PBT)(2)(CF3SO3)(2)] (2), and [Fe-II(PBI)(3)](CF3SO3)(2) (3)-catalyzed (PBO = 2-(2 '-pyridyl)benzoxazole, PBT = 2-(2 '-pyridyl)benzthiazole, PBI = 2-(2 '-pyridyl)benzimidazole) Baeyer-Villiger oxidation of cycloketones by dioxygen with cooxidation of aldehydes and peroxycarboxylic acids, including the kinetics on the reactivity of (mu-1,2-peroxo)diiron(III), acylperoxo- and iodosylbenzene-iron(III) species as key intermediates.
