(Picrylamino)‐1,2,4‐triazole Derivatives – Thermally Stable Explosives

Abstract

3-(Picrylamino)-1,2,4-triazole (PATO) and 3-amino-5-(picrylamino)-1,2,4-triazole (APATO) were synthesized and analyzed. During the syntheses of the compounds, two interesting side-products were isolated. The reactions of PATO and APATO with different nitrogen-rich bases, such as ammonia, hydrazine, triethylamine, and triaminoguanidine, resulted in the deprotonation of both triazole compounds and the formation of the corresponding salts (cation/anion ratio = 1:1). The compounds were obtained at ambient temperature in H 2 O or EtOH as qualitatively pure products with the characteristic properties of secondary explosives. The compounds were characterized by mul- Results and DiscussionSyntheses 3-(Picrylamino)-1,2,4-triazole (3) and 3-amino-5-(picrylamino)-1,2,4-triazole (13) were synthesized according to the literature [a]

Synthesis and Evaluation of 3‐Picrylamino‐1,2,4‐Triazole (PATO) Formulations

“…As shown in Scheme 1, the substitution is performed at 100 8C in DMF, and achieves near quantitative yield. If the solvent is purified to remove dimethyl amine then the product is free of the ring-N substitution product found by Chioato [4,5]. PATO has a strong tendency to retain bulk water and needs to be dried at elevated temperature or under reduced pressure if dry material is required.…”

Synthesis, characterization & in vitro antimicrobial‐antioxidant studies of novel N,1‐diphenyl‐4,5‐dihydro‐1H‐1,2,4‐triazol‐3‐amine derivatives

“…Among the triterpenes, the antimicrobial effects have been enhanced by the introduction of triazole ring . The naturally occurring bioactive triazoles‐based alcohol exhibited anti‐ Candida activity and cytotoxicity while quinoline‐substituted 1,2,3‐triazoles have shown great potential to inhibit the growth of Candida species, which is responsible for the mortality rates of mycoses . Mannich bases of 1,2,4‐triazoles have been screened for their antimicrobial properties.…”
