Synthetic Manifestation of Nitro Substituted Tetrazole-N-(Hetero)Aryl Derivatives and Energetic Studies
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. Most of the synthesized compounds show exothermic decomposition, and are consequently useful for energetic material applications.
