Abstract
Amidoximes (1) reacted with isopropenyl acetate in presence of KSF under microwave irradiation and gave 1,2,4-oxadiazoles (2). 1,2,4-Oxadiazoles (4) can also be obtained by microwave irradiation from O-acylamidoximes (3) adsorbed on Alumina. 1,3,4-Oxadiazoles (6) were obtained by irradiation of bis (acyl) hydrazines (5) in thionyl chloride.Keywords
