Abstract
1-Amino-5-nitriminotetrazole is synthesized for the first time via acid-catalyzed protection of 1,5-diaminotetrazole with acetone followed by aprotic nitration using N2O5 and in situ deprotection. The salts of 1-amino-5-nitriminotetrazolate are synthesized by addition of the corresponding bases. Most of the nitrogen-rich salts show insane explosive properties and compete with the most powerful non-nuclear explosives. The implementation of a fused triazolium cation yields a promising secondary explosive, with high performance but also low sensitivity and high thermal stability. Metal salts (K and Ag) are successfully used to initiate pentaerythritol tetranitrate using a classical detonator setup.
