Catalytic Application of Electrochemically Prepared Nickel Oxide Nanoparticles to Synthesize 2, 5–Disubstituted-1, 3, 4–Oxadiazoles

The present work aims to synthesize 2,5–disubstituted-1,3,4–oxadiazoles using electrochemically prepared nanoparticles of nickel oxide as catalyst. The nanoparticles thus prepared using electrochemical syntheses are in appreciable yield. The tetrabutyl phosphonium bromide has been used for capping followed by UV, FTIR, XRD, SEM EDS and TEM SAED studies for the characterization. The 2,5-disubstituted-1,3,4-oxadiazoles were synthesized from substituted benzoic acids and their hydrazides in microwave synthesis system using prepared nanoparticles as a catalyst.
