It was demonstrated by PMR spectroscopy that mixtures of N-oxides of 6- and 7- nitro derivatives are formed in the nitration of the N-oxides of 3-methyl-2- and 4-azafluorenes.The products were deoxygenated to give nitro derivatives of 2- and 4-azafluorenes.The N-oxides of nitro-substitited azafluorenes ware converted to salts of the aci forms by the action of alkali.
