The reactions beetwen 2,4-disubstituted thiosemicarbazides and orthoesters in refluxing xylene led to the formation of the 1,2,4-triazoline-5-thione ring and to the 1,2,4-triazolium-5-thiolate ring. The formation of the mesoionic componds is due to rearrangement of the easily available 2,4-disubstituted thiosemicarbazides to 1,4-disubstituted thiosemicarbazides under the reaction conditions adopted. This method can be usefully used for the synthesis of mesoionic compounds, especially in the case of the 2-methyl-4-phenylthiosemicarbazide.

A series of 5-aryl-2,4-dihydro-3H-1,2,4-triazole-3-thiones was prepared and evaluated for potential antidepressant activity.Members of this series were generally prepared by the alkaline ring closures of the corresponding 1-aroylthiosemicarbazides.Several

5-Aryl-2,4-dialkyl-2,4-dihydro-3H-1,2,4-triazol-3-ones may be converted in 55-74percent yield to the corresponding 3H-1,2,4-triazole-3-thiones by using the combination bis(tricyclohexylstannyl) sulfide/boron trichloride.
