Aminyl oxides 3, formed by oxidation of a mixture of nitrones 1 and primary amines 2, are converted into the secondary radicals 4 with increasing reaction time.In addition to dehydrogenation of 3 elimination of R2H is observed, starting with nitrones 1B - E.Radicals 10 and subsequently 4Ae arise from 1A and N-tert-butylhydroxylamine (15), but 17 is detected, too; from the reaction mixture the lead complex 14 can be isolated.Oxidative coupling of 2 with cyclic nitrones 20 and 28, respectively, affords aminyloxides 23 and 29 via their primary radicals.Further oxidation gives 24 and 30, respectively.From this reaction the lead complexes 25 can be isolated.
