The quaternization of 1- and 2-acetonyl-5-R-tetrazoles, as well as dimethyltetrazole, was accomplished under high pressure conditions (5000-14,000 kgf/cm2) by means of bromoacetone and methyl iodide and at atmospheric pressure and room temperature under the influence of methyl fluorosulfate.The structure of the salts were ascertained by 13C NMR spectroscopy, and the principles of the change in the chemical shifts and the spin-spin coupling constants during quaternization and protonation of the tetrazoles were studied.

Energetic salts comprised of substituted 1,2,4-triazolium and tetrazolium cations and 3,5-dinitro-1,2,4-triazolate anion were synthesized and characterized. The structure of 4,5-dimethyl-1-aminotetrazolium 3,5-dinitro-1,2,4-triazolate (16) was confirmed by X-ray analysis. Based on experimentally obtained heats of combustion, these materials have calculated heats of formation ranging from ΔHf° = 118 (2) to 778 kJ mol-1 (10) with densities >1.5 g cm-3. Salts, 2, 4, 7, 9 and 10, fall into the ionic liquid class (mp 100 °C). The Royal Society of Chemistry 2005.

Energetic ionic salts of azotetrazolate (AT), iminobis(5-tetrazolate) (IBT) and 5, 5′-bis(tetrazole) (BT) were synthesized; 1-methyl-4- aminotriazolium azotetrazolate has a layered structure and exhibits a heat of formation of 44360 kJ kg-1. The Royal Society of Chemistry 2005.
