Synthesis of derivatives of 1, 2, 4-triazole-3, 5-dicarboxylic acid

Chemistry of Heterocyclic Compounds, 1972
By oxidation of 3,5-dimethyl-1,2,4-triazole the monopotassium salt of 1,2,4-triazole-3,5-dicarboxylic acid was obtained. The mononitryl of 1,2,4-triazole-3,5-dicarboxylic acid was isolated during the reaction between 3-diazo-1,2,4-triazole-5-carboxylic acid and potassium cyanide in the presence of copper cyanide.

Infrared spectra and structure of some 3,5-diamino-1,2, 4-triazoles (guanazoles) [PDF]

open access: possibleChemistry of Heterocyclic Compounds, 1972
The IR spectra of guanazole and 1-methyl- and 1-phenylguanazoles have been recorded. A comparison of the IR spectra of the products before and after deuteration at the N-H bonds has shown that they have the diamino structure.

A new method of preparing 1, 2, 4-triazole carboxylic-3 acids

Chemistry of Heterocyclic Compounds, 1966
A new convenient method of preparing 1, 2, 4-triazole carboxylic acids-3 is worked out. Aminoguanidine bicarbonate and oxalic acid give 5-amino-1, 2, 4-triazole carboxylic acid-3, and this is converted, via the diazotriazole carboxylic acid and treatment of the latter with methanol, to 1, 2, 4-triazole carboxylic-acid-3.

Insights on the Antioxidant Potential of 1, 2, 4-Triazoles: Synthesis, Screening & QSAR Studies

Current Drug Metabolism, 2014
The aligned manuscript reports synthesis, screening and QSAR analysis of twenty six 1, 2, 4-triazole analogues from their respective aromatic carboxylic acids. The structures of synthesized analogues were characterized using physical and spectral analysis. 1, 2, 4-Triazole analogs antioxidant capacity was determined using DPPH radical scavenging assay.

1, 2, 4-Triazol-3-one and its nitro and amino derivatives

Chemistry of Heterocyclic Compounds, 1967
Some possible methods of preparation of 1, 2, 4-triazol-3-one are explored. A new method of preparing it from semicarbazide hydrochloride and formic acid is worked out. Nitration of the triazolone gives 5-nitro-1, 2, 3-triazol-3-one, whose structure is proved.

Synthesis of coumarinyl 1, 2, 4-triazoles in deep eutectic solvents

2019
1, 2, 3-Triazole and 1, 2, 4-triazole are two isomers of five-membered nitrogen containing heterocyclic compound. 1, 2, 4-Triazole derivatives are biologically active components with many human health positive effects (antibacterial, antifungal, antitumor, anticonvulsant, anti-inflammatory, antimicrobial).

Eco-friendly approach to synthesis of coumarinyl 1, 2, 4-triazoles

2019
1, 2, 4-triazoles, heterocyclic compounds with a wide range of biological activities such as antibacterial, antifungal, antitumor, anticolvulsant, antiinflammatory and antimicrobial, exists in two tautomeric forms, 1H and 4H. Until recently, these heterocycles are usually prepared from 1, 2, 4-oxadiazoles in reaction with hydrazine, 1, 3, 4-oxadiazoles
