A series of 1-2,4,6-trinitrophenylimidazoles and -1,2,4- triazoles has been prepared. These compounds have been chemically characterized by infrared spectroscopy, mass spectrometry, and 1H- and 13C-nuclear magnetic resonance NMR spectroscopy, and their physical and explosive properties have been examined. The measured densities correspond with those predicted, and increase with increasing the degree of nitration. The impact sensitivities are less than those of 1-2,4,6-trinitrophenylbenzotriazoles, but increase with the degree of nitration or increasing oxygen balance. Higher levels of nitration also induce reduced hydrolytic stability, and the desired 1-2,4,6- trinitrophenyl-2,4,5-trinitroimidazole and -3,5-dinitro-1,2,4-triazole could not be prepared. Extrapolation of the results obtained suggests that they would be quite sensitive explosives. Explosives, Synthesis, Imidazoles, Triazoles, Density, Sensitivity, Stability.
