, p. 583 - 585 (2000)
1,3-Bis(1,2,4-triazol-3-amino)-2,4,6-trinitrobenzene (BTATNB) has been synthesized by condensing 1,3-dichloro-2,4, 6-trinitrobenzene and 3-amino-1,2,4-triazole in dimethyl formamide (DMF) at 125 ± 2 °C. The product has been characterized by elemental analysis, Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR) and mass spectrometry. The data on thermal and explosive properties indicate that BTATNB is slightly more thermally stable than 3-picrylamino-1,2,4-triazole (PATO). At the same time, it is safer towards impact and friction.

Three new derivatives of 4,6-dinitrobenzofuroxan: 7-(4-nitrophenylamino)-4,6-dinitrobenzofuroxan, 7-(3,5-dinitrophenylamino)-4,6-dinitrobenzofuroxan and 7-(2,4,6-trinitrophenylamino)-4,6-dinitrobenzofuroxan, have been synthesised by condensing 4-nitroaniline, 3,5-dinitroaniline and 2,4,6-trinitroaniline with 7-chloro-4,6-dinitrobenzofuroxan, respectively. The characterisation of the compounds by IR, 1H-NMR, mass spectrometry and elemental analysis is described along with some of the evaluated preliminary explosive properties. The compounds were found to exhibit acceptable hazards properties. Furthermore, the thermal stability measurements indicated acceptable stability.
Chloro- and bromo-demethoxylation of methoxypolynitroaryl systems
Bellamy, Anthony J.,Hudson, P. Nick
, p. 5639 - 5642 (2007/10/03)
Various reagents for effecting halogenodemethoxylation of methoxy substituted polynitrophenyl and -biphenyl systems have been investigated, and the preferred procedures for achieving chloro- and bromo-demethoxylation in high yield have been identified.
Benzenepentamine - Its Easy Accessibility and Use in Syntheses of Pyrazinoquinoxalines
Praefcke, Klaus,Kohne, Bernd,Korinth, Frank,Psaras, Panicos,Nasielski, Jaques,et al.
, p. 617 - 622 (2007/10/02)
Benzenepentamine (6) has been rediscovered after about 60 years.A simple and very efficient synthetic route is described which yields the very sensitive, colourless 6 in methanolic solution in nearly quantitative yield.Condensations of 6 with two masked forms A and B of glyoxal conveniently lead to two types of amino-substituted pyrazinoquinoxalines, one with an angular phenanthrene-type topology (7a), or one with the linear anthracene-type structure (8a), respectively, with acceptable yields.The α-diketone benzil also reacts with 6, but less selectively, forming the corresponding tetraphenyl derivatives 7b and 8b of both these heterotricyclic ring systems.The heretofore unknown nitrobenzenepentamine (9), formed in addition to benzenehexamine in reduction reactions of 1,3,5-trinitrobenzenetriamine, has also been obtained.Based on spectroscopic data, the structures of these two multiamines have been deduced from their condensation products with α-diketones, in the case of the new pentamine 9 from its first derivatives 7c-e of pyrazinoquinoxaline.
