The acylhydrazones 3, obtained by the treatment of succinic acid dihydrazide 2 with furfural, nitrofurfuraldehydediacetate and substituted arylfurfurals, on oxidative cyclization with bromine in acetic acid yielded 1,2-bis(1,3,4-oxadiazol-2-yl)ethanes 4 which are further converted into 1,2-bis(4-amino-1,2,4-triazol-3-yl)ethanes 5 with hydrazine hydrate. The newly synthesised compounds are characterised by analytical, IR, NMR and mass spectral data. Most of the newly synthesised compounds have been found to be active against both Gram positive and Gram negative bacteria at less than 6 μg/mL concentration.
