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.
