A novel one-pot visible light irradiated synthesis of 1,3,4-thiadiazole from aldehydes and thioacyl hydrazides have been reported in presence of eosin Y as an organophotoredox catalyst at room temperature under aerobic condition. This synthesis includes a

A series of thioacylhydrazones of monocarbonyl compounds, which included the first representatives of previously unkonwn thioformyl- and thioacetyl-hydrazones, were synthesized.The effect of the structure on the position of the thioacylhydrazone-2,3-dihydro-1,3,4-thiadiazole ring-chain tautomeric equilibrium was studied by 1H and 13C NMR spectroscopy with the use of data for model compounds.In polar aprotic solvents a certain amount of the betaine tautomer appears in the equilibrium in individual cases in addition to the hydrazone and thiadiazoline forms.

According to data from the 1H and 13C NMR spectra in nonpolar media and the mass spectra, alkylidene derivatives of thiobenzhydrazide have a 1,3,4-thiadiazol-2-ine structure rather than a thiobenzhydrazone structure.The products of condensation of thioben
