A metal- and oxidant-free electrochemical method for synthesizing 1,2,3-thiadiazoles by inserting element sulfur into N-tosyl hydrazones is reported. This electrochemical transformation engages electrons as reagents to achieve redox processes, and avoid e

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.

An efficient I2/CuCl2-promoted one-pot three-component strategy for the construction of 1,2,3-thiadiazoles from aliphatic- or aromatic-substituted methyl ketones, p-toluenesulfonyl hydrazide, and potassium thiocyanate has been develo
