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

Convenient synthesis of 4H-1,2,4-triazole-3-thiols using di-2-pyridylthionocarbonate

Tetrahedron Letters, 2007
We report here the convenient synthesis of 4H-1,2,4-triazole-3-thiols using di-2-pyridyl-thionocarbonate as the thiocarbonyl transfer reagent. This method is suitable for microplate parallel synthesis and produces samples in screening-ready condition. It uses two large sets of building-blocks: amines and hydrazides.

Highly regioselective heterocyclization reactions of 1H-1,2,4-triazole-3-thiols with chloroacetylenephosphonates

Tetrahedron Letters, 2012
1-Chloroacetylene-2-phosphonates react with 1H-1,2,4-triazole-3-thiols in anhydrous acetonitrile with high regioselectivity to form the fused heterocycles, 6-(dialkoxyphosphoryl)-3H-thiazolo[3,2-b][1,2,4]triazol-7-ylium chlorides 1–5. A significant difference from the previously known reactions of binucleophiles with haloacetylenes is the involvement ...

An Acid Inhibitor Research: 5-Phenyl-1H-1,2,4-triazole-3-thiol

Protection of Metals and Physical Chemistry of Surfaces, 2019
The effect of 5-Phenyl-1H-1,2,4-triazole-3-thiol (5PTT) on the corrosion of mild steel which is used in the industry-widely, in hydrochloric acid solution was investigated as electrochemically and qualitatively. Inhibition efficiency of 5PTT on mild steel surface was studied by EIS, potentiodynamic polarization, SEM and FTIR techniques. The experiments

Cyanoethylation and carboxyethylation of 5-benzofuryl-4-substituted 4H-1,2,4-triazole-3-thiols

Russian Journal of General Chemistry, 2017
Base-catalyzed reactions of 5-benzofuryl-4-substituted 4H-1,2,4-triazole-3-thiols with acrylonitrile and acrylic acid afforded 2-(2-cyanoethyl)- or 2-(2-carboxyethyl)triazoline-3-thiones. Attempts to obtain the corresponding sulfanyl derivatives failed.
