The discovery of novel explosophoric building blocks for the construction of energetic compounds is extremely rare. Here, based on the comparative experimental properties and computational analysis of compounds where nitroaryl backbones were bonded with various nitrogen/oxygen-rich groups, it is shown that compounds having the azasydnone group possess higher density, detonation performance and thermal stability than their corresponding nitro, azido and tetrazole-analogs. All of these properties, as well as the oxygen balanced content of the "green" nitrogen rich endothermic unit make them an attractive explosophoric building block in the field of energetic materials chemistry.

Abstract: In this study, a new amino functionalized nano silica was synthesized using 2-hydroxy-1,2-diphenylethan-1-one. The new 2-hydroxy-1,2-diphenylethan-1-one@amino functionalized nano-silica was used as a support material for copper(II) catalyst. This composite was characterized by various techniques such as transmission electron microscopy, field emission scanning electron microscope, X-ray powder diffraction, inductively coupled plasma, energy dispersive X-ray spectroscopy, thermal gravimetric and FT-IR analysis and its particles size was estimated to be between 20 and 30?nm. The catalyst was tested in the N-heterocycles synthesis via C–N bond forming reactions. The catalyst displayed outstanding catalytic activity for all reactions under mild conditions. Finally, the nano heterogeneous copper catalyst is recoverable up to 12 times without any significant leaching which indicated that the heterogeneous catalyst is stable and very active under the applied conditions.

A direct synthetic protocol is developed for the synthesis of 1-substituted-1H-1,2,3,4-tetrazoles via a three-component condensation of primary amines, triethyl orthoformate and sodium azide in the presence of 5 mol% of trifluoromethanesulfonimide (HNTf2) in glycerol at room temperature with good to excellent yields.
