Synthesis and Characterization of Some Polynitro Imidazoles

초록

In continuing efforts, we focused on synthesizing nitroimidazoles consisted of dinitromethylene moiety as in FOX-7. 1-Methyl-5-nitro-2-trinitromethyl-1H-imidazole (1) was synthesized from the 2-(5-nitroimidazolyl)acetic acid (5), and also from its ethyl ester (6), and compound 1 was further converted to 1-methyl-5-nitro-2-(dinitromethyl)-1H-imidazole (2), and its potassium salt. In terms of the tautomerism, some parts of compound 2 existed in the imidazoline form.
