Re-examination of the thermal and photochemical decomposition of 2-azidophenazine reveals new pathways. Thus, besides reduction to the amine, the triplet nitrene yields the azo derivative and phenazino[1',2':5,6]pyridazino[4,3-a]phenazine while the s

Some properties of the heteropentalenes 5H-pyrazolo[1′,2′:1,2]-1,2,3-triazolo[5,4-a]phenazinyliumide (1) and 1,3-dimethyl-5H-pyrazolo[1′,2′:1,2]-1,2,3-triazolo [5,4-a]phenazinyliumide (2) are discussed. The u.v. absorption spectra of the free

The photochemistry of quinoline and isoquinoline N -oxides has been reexamined. 3, 1-Benzoxazepine, which had not been isolated as yet, was obtained from the former, while the formation of 1, 3-Benzoxazepine from the latter was demonstrated.

The dye-sensitized photo-oxidation of the title mesomeric betaine yields two pairs of epoxy-ketones and α,β-unsaturated ketones, formally arising from addition of singlet oxygen to its two 1,3-dipolar mesomeric forms (2a) and (2b); in methanol stab
