Synthesis of 1,2,4-triazole-3-thiols and their S-substituted derivatives

Russian Journal of Organic Chemistry, 2010
New 1,2,4-triazole-3-thiols were synthesized by reactions of the corresponding carboxylic acid hydrazides with isothiocyanates and subsequent cyclization of intermediate 1,4-substituted thiosemicarbazides. Alkylation of 1,2,4-triazole-3-thiols with benzyl chlorides and bromacetophenones gave only S-substituted derivatives.

Alkylation of 1,2,4-triazole-3-thiols with haloalkanoic acid esters

Russian Journal of Organic Chemistry, 2017
Alkylation of 4,5-disubstituted 4H-1,2,4-triazole-3-thiols with methyl chloroformate and ethyl chloroacetate chemoselectively afforded the corresponding S-alkyl derivatives, whereas the alkylation of 5-benzyl-4-phenyl-4H-1,2,4-triazole-3-thiol with methyl 3-bromopropanoate gave an inseparable mixture of S- and N-alkylation products. Hydrazinolysis of S-

Electrochemical, ToF-SIMS and computational studies of 4-amino-5-methyl-4H-1,2,4-triazole-3-thiol as a novel corrosion inhibitor for copper in 3.5% NaCl

Journal of Molecular Liquids, 2019
In the present work, 4-amino-5-methyl-4H-1,2,4-triazole-3-thiol (AMTT) was synthesized and characterized using FTIR and 1H NMR. The triazole was for the first time investigated as a novel corrosion inhibitor for copper in 3.5% NaCl solution employing the

Alkylation and aminomethylation of new 4,5-Substituted 4H-1,2,4-Triazole-3-thiols

Russian Journal of Organic Chemistry, 2013
We previously synthesized 5-[alkoxyphenyl(alkoxyphenethyl, benzofuryl)]-4-phenyl(allyl)-4H-1,2,4triazole-3-thiols some of which (specifically Nand S-substituted derivatives) were found to exhibit antitumor activity [1]. While continuing studies in this line, we tried to find new efficient compounds among substituted 1,2,4-triazole-3-thiols and reveal a

Analytical application of the poly(1H-1,2,4-triazole-3-thiol) modified gold electrode for high-sensitive voltammetric determination of catechol in tap and lake water samples

International Journal of Environmental Analytical Chemistry, 2019
In this work, a simple, sensitive and rapid method for the determination of trace amounts of catechol (CT) in aqueous media has been suggested. For this purpose, poly(1H-1,2,4-triazole-3-thiol) film was electrochemically deposited successfully at the ...
