Potassium fluoride was found to be an efficient catalyst and solid support for the synthesis of 3,5-disubstituted-1,2,4-oxadiazoles. In this work, a one-pot method for the synthesis of these compounds from the reaction of nitriles with hydroxylamine hydrochloride and acyl chloride in the presence of potassium fluorideundersolvent-free conditions using microwave irradiation has been developed.

The first example of a one-pot tandem approach for the synthesis of 3,5-disubstituted-1,2,4-oxadiazole derivatives frombenzylhalides and amidoxime is reported. Derivatives of 3,5-disubstituted 1,2,4-oxadiazole were obtained in excellent yields under mild conditions using DMSO in the absence of an additional oxidant. Benzyl bromides bearing a range of substituents proved to be suitable substrates
