3,4-Disubstituted-5-mercapto-1,2,4-triazoles and Related Compounds

3,4-Diaryl-5-mercapto-1,2,4-triazoles have been prepared by the cyclization of the corresponding 1-aroyl-4-Substituted thiosemicarbazide with alkali. The resulting mercapto triazoles were converted into 3,4-disubstituted-5-alkylthio-1,2,4-triazoles with the action of different alkyl halides and some of the sulphides were converted into sulphones by oxidation with aqueous potassium permanganate.
