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.
A recyclable catalytic system under heterogeneous phase-transfercatalysisconditions was designed by using polyacrylamide-bound tungstate. A convenient method for the oxidative direct transformation of benzilic amines to carbonyls with hydrogenperoxide was then developed.
