Synthetic manifestation of nitro substituted tetrazole-N-(hetero)aryl derivatives and energetic studies

A workable cost-efficient synthetic method for the construction of nitro substituted 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 a –NO2 or a –NHNO2 group, exhibit energetic properties close to RDX, but with enhanced insensitivity. Most of the synthesized compounds show exothermic decomposition and are consequently useful for energetic material applications.
