Abstract

The spin adducts formed under UVA irradiation or in the presence of mild oxidants in the reaction of a number of heteroaromatic bases and two indolic nitrones have been characterized by means of ESR spectroscopy. The formation of the spin adducts is explained via the Forrester–Hepburn mechanism, while the occurrence of inverted spin trapping is excluded. Photolysis of nitrones 1 and 2 or of the corresponding cyclic hydroxamic acids resulted in the formation of the related acyl nitroxides.
