Abstract

Abstract A convenient, one pot procedure is reported for the synthesis of a variety of 2, 5- disubstituted-1, 3, 4-oxadiazoles by condensing mono-arylhydrazides with acid chlorides in HMPA solvent under the microwave heating. The yields are good to excellent, the process is rapid and does not need any added acid catalyst or dehydrating reagent.
