Aromatic azapentalenes. III. 1,3a,6,6a-Tetraazapentalenes

Advances in science and technology of modern energetic materials: An overview

“…Nitration reactions and synthesis of nitro compounds have an immense importance in the synthetic organic chemistry [106]. Nitro compounds are widely used as chemical feedstock and also for synthesis of medicines, dyes, perfumes, anticancerous drugs, fertilizers, plastics and explosives [107,108].…”

A review of advanced high performance, insensitive and thermally stable energetic materials emerging for military and space applications

“…The compounds have decomposition temperature point of 340 and 396 • C respectively and both have a crystal density of 1.88 g/cm 3 . They are significantly more energetic than TACOT while retaining excellent thermal stability [100].…”

Synthesis, Thermal Stability and Impact Stability of Novel Tetranitro-Dipyridotetraazapentalene Derivatives

“…Because of the inherent thermal stability of the dibenzotetraazapentalene ring system, 2,4,8,10-tetranitrodibenzotriazolo[1,2-a]benzotriazol-6-ium inner salt (1, yTacot) (5) was initially identi®ed as an attractive precursor for the development of a new class of high density insensitive energetic materials which possess low sensitivity to thermal decomposition and detonation by impact (6) . To this end, we recently reported the synthesis of 4,8-dinitro-12H-[1, 2,5]oxadiazolo [3,4- (2) . However, it was discovered that (2) and related isomers were signi®cantly more sensitive to impact than the corresponding tetranitrodibenzotetraazapentalene analogs (2) .…”
