2,6-Diamino-3,5-dinitropyridine 1-oxide has been prepared by mixed acid nitration of 2,6-diaminopyridine, followed by oxidation using hydrogen peroxide in acetic acid. 3,5-Dinitro-2,4,6-triaminopyridine has been prepared by oxidative amination of 2-chloro-3,5-dinitropyridine or 2,6-diamino-3,5-dinitropyridine using potassium permanganate in liquid ammonia, or by "vicarious nucleophilic amination" of 2,6-diamino-3,5-dinitropyridine using hydroxylamine in aqueous potassium hydroxide. 3,5-Dinitro-2,4,6-triaminopyridine 1-oxide has been prepared by oxidation of 3,5-dinitro-2,4,6-triaminopyridine using hydrogen peroxide in acetic acid, and by "vicarious nucleophilic amination" of 2,6-diamino-3,5-dinitropyridine 1-oxide. Nmr spectroscopy and single crystal X-ray diffraction studies have shown that these compounds have the planar structures and intra- and inter-molecular hydrogen bonding necessary to confer on the materials the high density, the thermal and chemical stability, and the explosive insensitivity required for new insensitive energetic materials.

Paragraph 0008; 0021; 0027-0029, (2018/03/28)
The invention relates to a method for compounding 2,6-diamido-3,5-binitro pyridine-1-oxide. The method comprises the following steps: acetylizing 2,6-diamido-3,5-binitro pyridine into a soluble acetylate product by utilizing acetic anhydride, and then oxidizing the acetylized 2,6-diamido-3,5-binitro pyridine by using hydrogen peroxide and hydrolyzing, thereby acquiring 2,6-diamido-3,5-binitro pyridine-1-oxide. The method provided by the invention has the characteristics of short reaction time, no solid catalyst residue and simple effluent composition. The method is used for compounding the 2,6-diamido-3,5-binitro pyridine-1-oxide.

Nitration of amino- and diaminopyridines and -picolines led, in unexpected one-step reactions, to dinitrated derivatives.Dinitropicolines gave styrylpiridines, and 2-amino-6-hydroxy-3,5-dinitropyridine was transformed by the thermolysis of its azido deriv
