Summary: A strategy for synthesizing nitrogen-rich energetic materials with good properties is reported, taking advantage of the synergetic effects of inter- or intramolecular hydrogen bonds. A new thermostable and insensitive material, 1,2-dihydrazono-1,2-di(1H-tetrazol-5-5-yl)ethane, was obtained from the reaction of dioxime with hydrazinehydrate. The material has reduced acidity, low solubility in water, high nitrogen content (76%), high thermal stability (275°C), and insensitivity to external stimuli.

Summary: The ever-growing demand for cleaner and higher-performing energetic materials has led to a quest to replace toxic metal-based traditional energetic compounds. This review examines strategies for the design and synthesis of next-generation nitrogen-rich, green primary explosives, focusing on potassium-based energetic salts, metal-free ionic energetic salts, and metal-free covalent energetic materials. Different combinations of nitrogen-rich frameworks and energetic substituents are highlighted for their explosive performance, initiability, safety, and environmental impact, along with key parameters associated with energetic materials.

Summary: The Ru(dppbsa)-catalyzed reductive amination of ketones with nitroarenes and nitriles using H-2 as the hydrogen surrogate has been developed. It was found that both reactions proceed through reduction of nitroarenes or nitriles to amines, followed by condensation with ketones to form imines and subsequent hydrogenation. However, the possibility of formation of an amino-ligated Ru complex and in situ nucleophilic C-N coupling during the reduction cannot be completely ruled out. This versatile method allows for good functional group tolerance and provides a new design platform for homogeneous catalysts in the synthesis of secondary amines.

Summary: This paper synthesized and characterized a series of energetic ionic liquid plasticizers. The results showed that these compounds, particularly the ester-functionalized cations, were suitable as plasticizers for hydroxyl-terminated polybutadiene (HTPB) curing systems, improving the tensile strength and elongation at break. The ester-functionalized ionic liquids also reduced the glass transition temperature of HTPB elastomers, and the storage modulus varied depending on the anions present. The crosslink densities of HTPB/TDI/2a and HTPB/TDI/2b plasticized by ester-functionalized ionic liquids were larger.
