The nitration of 5H-phenanthridin-6-one (I), 5H-phenanthridin-6-one-10-carboxylic (II) and 5H-phenanthridin-6-one-1-carboxylic acids (III), 4H-cyclopentaphenanthridine-5,9-dione (IV), 4H-cyclopentaphenanthridine-5-one (V), 5,10-dioxo-4,5,9,10-tetrahydro-4,9-diazapyrene (VI), and 5,9-dioxo-4,5,9,10-tetrahydro-4,10-diazapyrene (VII) with nitric acid (sp. gr. 1.42-1.51) and a nitrating mixture of 0-120 deg C was investigated.The orientation and sequence of incorporation of nitro groups in I-VII are determined by the presence of a phenanthridone structure in them.Mono-, di-, tri-, and tetranitro-substituted I-VII were obtained and characterized.
