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.

Synthesis of new 4,5-substituted 4H-1,2,4-triazole-3-thiols and their sulfanyl derivatives

Russian Journal of General Chemistry, 2015
Reaction of hydrazides of 4-alkoxybenzoic acids with benzyl isothiocyanate followed by cyclization with thiosemicarbazide afforded a series of new 4,5-substituted 4H-1,2,4-triazole-3-thiols. S-Alkylation of the latter led to the formation of the corresponding 4,5-substituted sulfanyl derivatives of 4H-1,2,4-triazoles.

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.

Regioselectivity of the reaction of 4H-1,2,4-triazole-3-thiol derivatives with chloroethynylphosphonates and structure of the products

Russian Journal of Organic Chemistry, 2013
Chloroethynylphosphonates reacted with 4H-1,2,4-triazole-3-thiols in anhydrous acetonitrile to afford fused heterocyclic compounds, 6-(dialkoxyphosphoryl)-3H-thiazolo[3,2-b][1,2,4]triazol-7-ium chlorides, with high regioselectivity. The products were converted into inner salts (zwitterions) of the corresponding phosphonic acids or their monoesters with
