Activation of Molecular Oxygen into Hydrogen Peroxide via α-Azobenzyl Hydroperoxide. A Generation of Hydrogen Peroxide from Organic Hydroperoxide by the Amine-base Catalyzed Reaction

Hydrogen peroxide is generated together with nitrile imine from α-azobenzyl hydroperoxide, which is formed readily by autooxidation of arylaldehyde hydrazone, via peroxycarboximidic acid by the amine-base catalyzed reaction in benzene. This provides a new type of activation reaction of molecular oxygen into hydrogen peroxide by aldehyde hydrazone.
