Safe Synthesis of TKX‐50 Using an Insensitive Intermediate

Abstract

Abstract Dihydroxylammonium 5,5’‐bistetrazole‐1,1’‐diolate (TKX‐50) has been evaluated as a promising energetic material, but its synthesis involves a sensitive intermediate, diazidoglyoxime (DAG). Ditetrahydropyranyl diazidoglyoxime (THP‐DAG, 5 ) was introduced to replace DAG as an insensitive intermediate, and TKX‐50 was obtained via 5,5′‐bistetrazole‐1,1′‐diol dihydrate (1,1‐BTO). All compounds were characterized using NMR and mass spectroscopy as well as impact, friction, and electrostatic discharge sensitivity measurements.
