Abstract
We reported a three-component, simple, one-pot and novel method for the synthesis of 1,2,4-triazole-3-thione derivatives from the condensation of ammonium thiocyanate and aroyl chlorides with ethyl carbazate under solvent-free conditions. The structures of compounds were deduced from elemental analysis and their IR, 1H NMR, 13C NMR spectra. This new protocol offers advantages such as mild reaction conditions, short reaction time, easy work-up, high yields and does not involve any hazardous solvent. Therefore, this procedure could be classified as green chemistry.
