transformations in synthetic chemistry.[1] Recently, much attention has been paid to the
development of homogeneous [2] and heterogeneous [3] catalysts for the highly efficient
oxidation of alcohols using molecular oxygen (O2) as the oxidant because of the necessity
of replacing stoichiometric reactions involving toxic oxidants such as chromium and
manganese salts with environmentally benign catalytic oxidation systems [Eq.(1)].[4] …
