on the development of nitrogen-rich heterocyclic energeticsalts that should have low vapor pressure, higher density and better thermal stability. To extend the scope of triazolium based ILs, we have synthesized different aryl substituted, 4-amino1-ethyl-3-mercapto-5-phenyl-4H-[1,2,4]triazol-1-ium salts. The synthesis of ionic liquids and saltsbased on 4-amino-1,2,4-triazole has been done as shown
离子液体 (IL) 或有机离子盐由有机阳离子和无机或有机阴离子组成。在 100°C 或低于 100°C 熔化的离子盐被称为离子液体。这些分子显示出特殊的特性,例如低蒸气压、宽温度范围内的流动性、高热稳定性、离子导电性、结构可设计性和溶解各种化学物质的能力。It is possible to form any specific IL's composition depending on one's needs, and the desired chemical and physical properties can be realized in a single salt, by proper selection of the component ions. 因此,离子液体的多功能性通过选择合适的离子组合而产生。IL 在化学和材料科学的几乎每个分支中都很普遍,包括催化、有机合成、分离和分析、

A series of novel Schiff bases containing both a 1,2,4-triazole and deoxycholic acid skeleton have been synthesised in excellent yields and in high purity by means of microwave irradiation. The structures of the target compounds were characterised by MS, IR and NMR as well as elemental analysis. All the products were evaluated for their in vitro antibacterial activities against Gram positive (Staphylococcus

Twelve novel triazolothiadiazole derivatives were synthesized from 4-amino-5-substituted-4H-1,2,4-triazole-3-thiols with various aromatic carboxylic acids by cyclization in the presence of phosphorous oxychloride. All the newly synthesized compounds were characterized by FTIR, 1H NMR, mass spectroscopy and elemental analysis. The antimicrobial activities of the title compounds were examined by disc diffusion method against Escherichia coli, Staphylococcus aureus, Pyricularia oryzae and Rhizoctnia solani. The bioassay indicated all synthesized triazolothiadiazole derivatives possessed moderate to good antibacterial and antifungal activities against the tested organisms. Especially, compounds 2e and 2k exhibited excellent antibacterial and antifungal activities among these triazolothiadiazole derivatives.
GRAPHICAL ABSTRACT ABSTRACT Twelve cyclanone O-(2-(3-aryl-4-amino-4H-1,2,4-triazol-3-yl)thio)acetyl)oxime derivatives were synthesized and their structures were confirmed by spectroscopy (IR, 1H NMR, 13C NMR, 19F NMR) and elemental analysis. Their antifungal and antibacterial activities were evaluated against six fungi (Gibberella zeae, Fusarium oxysporum, Clematis mandshurica, Phytophthora infestans
