Abstract
1- and 2-Propargyl-tetrazole (1- and 2-PryTz) were synthesized by reaction of propargyl bromide with sodium tetrazolate and used as ligands in energetic coordination compounds (ECCs) and evaluated concerning their thermal and mechanical sensitivities. Furthermore, the two nitrogen-rich compounds 1-((1H-1,2,3-triazol-4-yl)methyl)-1H-tetrazole (TriMT, 3) and 1-((1-(2-(1H-tetrazol-1-yl)ethyl)-1H-1,2,3-triazol-4-yl)methyl)-1H-tetrazole (TriMTET, 4) were prepared. Both were characterized by IR spectroscopy, NMR measurements, and low-temperature X-Ray diffraction analysis. Due to the highly endothermic enthalpy of formation of the propargyl-tetrazole ligands, powerful, yet relatively safe to handle, laser-ignitable ECCs were obtained.
