Abstract:2-Chloro-4,5-dinitro-1H-imidazole was synthesized through the nitration of 2-chloro-4-nitro-1H-imidazole. Then it reacted with ammonium hydroxide to give 2-chloro-4-nitro-1H-imidazol-5-amine with an overall yield of 67.8%. These two products were characterized using mass spectrometry and infrared spectroscopy. Charge distribution in 2-chloro-4,5-dinitro-1H-imidazole obtained from NBO analysis was consistent with the ammoniation results. |
Key words:2-chloro-4,5-dinitro-1H-imidazole; nitration; ammoniation; NBO analysis |
