Selective transformations of 2-(p-toluenesulfonyl)-N-tosylhydrazones with different sulfur sources have been established. A series of 4-aryl-1,2,3-thiadiazoles and novel 4-aryl-5-tosyl-1,2,3-thiadiazoles were selectively constructed by the adjustment of reaction conditions. These protocols feature short reaction time, good compatibility of functional group, easily available materials, and good selectivity.
