Amidoximes reacted with isopropenyl acetate in presence of KSF under microwave irradiation and gave 1,2,4-oxadiazoles. 1,2,4-Oxadiazoles can also be obtained by microwave irradiation from O-acetylamidoximes absorbed on Alumina. 1,3,4-Oxadiazoles were obta

A new synthesis of symmetrical 2,5-disubstituted 1,3,4- oxadiazoles

Several new 2,5-disubstituted 1,3,4-oxadiazoles have been synthesized in good yields by reaction of aromatic acids with hydrazine dihydrochloride in a mixture of orthophosphoric acid, phosphorus pentoxide and, in general, with addition of phosphorus oxychloride to the reaction mixture. The structures of new oxadiazoles derivatives were confirmed by analytical and spectral data.
