It is suggested that photolysis of 1-benzyl-2-ethylbenzimidazole 3-oxide (I) involves two different pathways ; one goes via an oxaziridine intermediate (VI) formed from the excited singlet state ; and the other is deoxygenated via the excited triplet state, enhanced by the presence of benzophenone or anthraquinone. Deoxygenation of several aromatic N-oxides is shown to be effected by anthraquinone.
