摘要：

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.
