The one pot, three-components condensation of aromatic aldehydes, hydrazine and sulfur in ethanol under microwave irradiation provided symmetrically 3,5-disubstituted 1,3,4-thiadiazoles in high yields and good purity. This reaction must be conducted under pressure of hydrogen sulfide produced in-situ. The structure of the compounds was confirmed by 1H, 13C NMR, MS and elemental analysis.
