Summary: The preparative access to and first group 10 metal complexes of novel 1H-1,2,3-triazole-4,5-dithiolate ligands (tazdt(2-)) are reported. A set of S-protected 1H-1,2,3-triazole-4,5-dithiol derivatives were synthesized by a 1,3-dipolar cycloaddition catalysed by either Ru(ii) or Cu(i), and the removal of benzyl groups was found to be superior. Coordination of these ligands led to the formation of various metal complexes. The properties of the Ni and Pd complexes were determined by spectroscopy and calculations.

Summary: Two energetic molecules with different linear and branched N8 structures were synthesized, showing a significant difference in decomposition temperatures despite having the same chemical formula and azo functionality. Analysis based on single crystal X-ray diffraction and theoretical investigations revealed that regional heterogeneity causing difference in charge distribution is the main factor contributing to the varying stabilities of these molecules.

Summary: Electrochemical synthesis is being used to create new strategies for the assembly of complex organic molecules. However, forming N-N bonds electrochemically is still challenging due to the electronegativity of nitrogen and side reactions. In this study, a green electrochemical approach was presented to selectively form N-N bonds using oximinohydrazones. The resulting 1,2,3-triazole 1-oxides possess thermally stability and show promise for the development of functional organic materials and pharmaceutical ingredients.

Summary: 1,1-Dibromoalkenes can be directly used as precursors for the synthesis of 5-substituted 1,2,3-triazoles. Three different approaches, dependent on the N1 substituent, were developed to access various 1,2,3-triazole products. Treatment of 1,1-dibromoalkenes with n-butyllithium and reaction with a sulfonyl azide yielded 5-substituted 1-sulfonyl-1,2,3-triazoles. Reaction of the lithium base with zinc followed by reaction with aryl azides provided access to 1-aryl-1,2,3-triazoles. Lastly, the use of EtMgBr as base and reaction with an alkyl azide afforded 1-alkyl-1,2,3-triazoles.

Summary: A series of Phthalimide/Naphthalimide containing 1,2,3-triazole hybrids were synthesized through Click reaction. The compounds were characterized using various spectral techniques and the structure of compound 6b was confirmed by Single Crystal X-ray Crystallography. The synthesized hybrids showed excellent antimicrobial potency, particularly compound 6e, which demonstrated strong antimicrobial activity against all tested strains due to the presence of a nitro group on the phenyl ring. Molecular docking studies confirmed the binding conformation of compound 6e with E. coli topoisomerase II DNA gyrase B.

Summary: Designing and developing new energetic materials with lower sensitivity and higher energy is a challenging and meaningful task. The key problem in designing new insensitive high-energy materials is how to skillfully combine the characteristics of low sensitivity and high energy. A strategy of N-oxide derivatives containing isomerized nitro and amino groups was proposed based on a triazole ring framework to answer this question. The study results showed that the NATNOs have relatively stable properties, excellent detonation properties, and potential as high detonation velocity energy materials. The strategy of nitro amino position isomerization coupled with N-oxide is an effective means to develop new energetic materials.

Summary: In recent years, azole-rich energetic compounds have become a research hotspot due to their excellent properties. This review provides a comprehensive summary of the physicochemical and energetic properties of various energetic materials, emphasizing the relationship between thermal stability and the structural, physicochemical, and energetic properties of azole-rich energetic compounds. Five aspects, including functional group modification, bridging, preparation of energetic salts, energetic metal-organic frameworks (EMOFs), and co-crystals, can be considered to improve the thermal stability of compounds. It has been demonstrated that increasing the strength and number of hydrogen bonds of azoles and expanding the π-π stacking area are the key factors to improve thermal stability, which offers a valuable way to develop energetic materials with higher energy and thermal stability.
