Heat-resistant energetic compounds are of great importance in the field material chemistry. Here, we report a practical synthesis series fused-ring via combination 1,2,3-triazine N-oxide and 2,4,6-trinitroaniline moieties. Starting from known compound 4,6-diamino-2-chloropyrimidine-5-carbonitrile (1), nucleophilic substitution followed by one-step nitration introduced three nitro groups onto benzene ring moiety, simultaneously. The resulting 4-7 exhibited high decomposition temperature (Td > 250 °C) as well relatively good detonation properties low sensitivities.

Abstract We herein present a chemo- and regioselective methodology for the N-alkylation/arylation of azoles (imidazoles, pyrazoles, triazoles) using 5-bromo-1,1,1-trifluoro-4-alkoxypent-3-en-2-ones (brominated enones) as precursors, in order to selectively obtain N-alkylated containing disubstituted furans or dihydrofurans. The key reaction steps are 1,4-conjugated addition followed by nucleophilic substitution (each promoted different nitrogen atom azole), which furnish corresponding 2,5-disubstituted dihydrofurans (24 examples, yields 37–97%). limitations explored it is found that when 2-chlorobenzimidazole used dinucleophile, 5-trifluoromethyl-3-substituted obtained (three 57–67%). selectivity reactions determined through NMR analysis (including two-dimensional techniques 15N nucleus) single-crystal X-ray analysis.

Revamping the structure of energy storage is an efficient strategy for striking a balance between performance and sensitivity energetic materials to achieve high reduced sensitivity. In continuation prior research, this study utilized ligand 3,5-dimethyl-1H-pyrazole-4-carbonhydrazide (DMPZCA) innovatively designed synthesized compound ECCs [Cu(HDMPZCA)2(ClO4)2](ClO4)2·2H2O (ECCs-1·2H2O). Compared with former solvent-free ECCs-1 refers innovative material characterized by dual involving ionic salts coordination compounds. Due these unique structures, exhibits increased [ClO4-] content, higher oxygen constant (OB = -7.9%), improved mechanical (IS 8 J, FS 32 N). Theoretical calculations support superior detonation ECCs-1. Additionally, experimental results confirm its ignition capability through lower-threshold lasers highlight outstanding initiation potential explosive power, making it suitable candidate primary explosives.

Polymorphism is universal in energetic materials (EMs), which originated from the differences of molecular conformers and stacking mode. The polymorphic transition may lead to change crystal structure properties EMs. In this work, β-Hx2TNBI·2H2O (β-1) was successfully synthesized through solvent-induced conformational Hx2TNBI·2H2O. From perspective quantum chemistry dynamics, changes caused by different conformations are discussed detail, leads difference results show that β-1 featured wave-like stacking, making it less sensitive external mechanical stimuli than α-Hx2TNBI·2H2O (α-1) (α-1: IS > 6 J, FS 288 N; β-1: 20 360 N). α-1 better aromaticity, gives higher thermal stability Td = 186 °C; 146 °C). Simultaneously, compared with β-1, has density detonation performance. This work provides a new effective way safety
