The condensation reaction of thiobenzamide, (as well as thionicotinamide and isothionicotinamide) in the presence of dimethyl sulfoxide and of an acid, affords 3,5‐diphenyl‐1,2,4‐thiadiazole. Under the same experimental conditions, N‐substituted thioureas are also condensed to 1,2,4‐thiadiazole derivatives; their structure is ascertained by spectroscopic properties and by X‐ray diffraction. Some information on the mechanism of thiadiazoles formation from both starting classes of compounds, thiobenzamides and N‐substituted thiourea, is collected and discussed.
