A convenient method for the synthesis of 1,2,4-triazol-3-imines through a selective, formal, 1,3-dipolar cycloaddition of organo-cyanamide ions with nitrile imine dipoles is reported. Hydrolysis of the 1,2,4-triazol-3-imines yields the corresponding 1,2,4-triazol-5-ones. A stepwise mechanism, supported by DFT calculations, is invoked to explain the reaction selectivity.

This work described a one-pot tandem three-component synthesis of 2,4,5-triaryl-2,4-dihydro-3H-1,2,4-triazol-3-ones using a simple reaction between phenylhydrazines, benzaldehydes and phenyl isocyanates under microwave irradiation and solvent-free conditi
Reactions of Sulfur Monochloride with some Aromatic Aldehyde Semicarbazones and Thiosemicarbazones: New Syntheses of Substituted 2,4-Dihydro-1,2,4-triazol-3-ones, 2,4-Dihydro-1,2,4-triazole-3-thiones and 2-Amino-1,3,4-oxadiazoles

Treatment of various substituted semicarbazones of aromatic aldehydes with sulfur monochloride yields the corresponding substituted 2,4-dihydro-1,2,4-triazol-3-ones.With thiosemicarbazones, the products are derivatives either of the 2-amino-1,3,4-thiadiaz
Oxidation of Aldehyde Semicarbazones with Lead Dioxide: Application to the Syntheses of 2-Amino-1,3,4-oxadiazoles and 2,4-Dihydro-1,2,4-triazol-3-ones
