The formation of oxaziridines and the isomeric amides in equal amounts by the spontaneous autoxidation of several liquid imines via peroxyimidic acid intermediates is reported. ... Imine derivatives of aldehydes and ketones are widely used as simple intermediates both in chemical and enzyme-catalysed syntheses. While the susceptibility of imines to hydrolysis is well documented, to date there appear to be very few reports on the autoxidation reactions of ...
