  2-Alkenyl-1,3,4-oxadiazole derivatives have been prepared by cross-coupling of 1,3,4-oxadiazoles with styrenes by using palladium(II) trifluoroacetate [Pd(TFA)2] as a catalyst, 1,10-phenanthroline as a ligand, silver trifluoroacetate as an oxidant, and toluene as a solvent. The products were formed in high yields and no byproducts were detected.

  Mechanochemical synthesis of 2,5-disubstituted 1,3,4-oxadiazoles was developed as an environmentally benign alternative to conventional solvent-based methods. In the presence of triphenylphosphine and trichloroisocyanuric acid, N-acylbenzotriazoles condense with acylhydrazides leading to oxadiazoles derivatives in good to excellent yields within minutes. The approach circumvents the need for strictly

  2,5-二取代 1,3,4-恶二唑的机械化学合成被开发为一种环境友好的替代传统溶剂方法的方法。在三苯基膦和三氯异氰脲酸存在下，N-酰基苯并三唑与酰肼缩合，在几分钟内以良好至极好的收率生成恶二唑衍生物。该方法避免了对严格无水条件、外部加热、长反应时间以及繁琐的多步骤程序的需要。一系列具有反应性功能的底物也具有良好的耐受性。

  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.
