Synthetic manifestation of trinitro-pyrazolo-2H-1,2,3-triazoles (TNPT) as insensitive energetic materials† This study showcases the design and development of a facile method for synthesizing trinitro-pyrazolo-triazole (TNPT) and its derivatives. The synthesized compounds are analysed using multinuclear NMR [1H, 13C, and 15N] and HRMS analyses. Furthermore, X-ray diffraction studies confirm the structure of some TNPT derivatives.

A workable cost-efficient synthetic method for the construction of a wide range of tetrazole-N-aryl/heteroaryl derivatives is discussed here. The energetic functional groups -NO2, -NHNO2 and -N3 are reliably inserted into the molecular backbone, making the tetrazole-N-aryl derivatives highly energetic and insensitive to heat and impact. For example, the tetrazole derivatives 7 and 8, bearing -NO2 or a -NHNO2 group, exhibits energetic property close to RDX, but with enhanced insensitivity.
