Abstract

Abstract : The easy synthesis of graphene oxide (GO)‐supported manganese dioxide (MnO2 ) nanoparticles as a stable heterogeneous nanocatalyst (MnO2 @GO) is described. This catalyst was investigated in the synthesis of 1, 2, 4‐oxadiazoles from amidoximes and aldehydes via a cyclization and oxidation process. The nanocomposite was prepared and characterized using various techniques. The catalytic application of the nanocomposite was examined in the reaction of a variety of aldehydes with aliphatic and aromatic amidoximes. The stable and robust catalyst was recycled for seven consecutive runs without a significant decrease in the catalytic activity.
