- Abstract
The condensation reaction of 4-formyl-3-methylfuroxan with 1,5-diaminotetrazole led to 4-(1-amino-5-aminotetrazolyl)methyleneimino-3-methylfuroxan ( 1) in high yield. Its structure was confirmed by an X-ray diffraction study. 4-(1-Amino-5-nitriminotetrazolyl)methyleneimino-3-methylfuroxan ( 2) was obtained through the nitration of 1 with 100 % HNO3. The nitrogen-rich salts of 2 with bases such as 1-amino-1,2,3-triazole ( 3), 4-amino-1,2,4-triazole ( 4), and 3-amino-1,2,4-triazole ( 5) were synthesized and characterized by IR, Raman, and NMR spectroscopy and elemental analysis. In addition, the structures of 2, 4, and 5 were further confirmed by single-crystal X-ray diffraction analyses. Compound 5 decomposes at 183 °C, whereas 3 and 4 are less stable and decompose at 139 and 164 °C, respectively. The heats of formation, detonation parameters, and impact sensitivity of 1- 5 were investigated by theoretical and experimental methods.
