Peroxotungstophosphate (PCWP) was found to be an efficient catalyst for the oxidation of amines with 35% H2O2 under the biphasic or homogeneous condition. Thus, primary and secondary amines were oxidized to oximes and nitrones, respectively, in good yields. Aromatic amines afforded to the corresponding nitroso compounds and/or nitrobenzenes.

The methyltrioxorhenium-catalyzed oxidation of secondaryamines and primaryamines with hydrogen peroxide has been carried out. The oxidation of secondaryamines afforded nitrones in good-to-excellent yield. Benzylamines were selectively oxidized to oximes, while general primary alkylamines possessing the α-C–H bond gave mixtures of oximes, nitroso dimers, and azoxy compounds.

An oxidation catalyst for use in the oxidation of a substrate with a molecular oxygen, comprising at least one member selected from the group consisting of a specific hydrazyl radical (such as 2,2-diphenyl-1-picrylhydrazyl) and a specific hydrazine compound (such as 2,2-diphenyl-1-picrylhydrazine). A method for producing a chemical compound, comprising contacting a substrate with a molecular oxygen in the presence of the above-mentioned oxidation catalyst.
