  Abstract 2-Aryl- and 2-alkenyl-1,3,4-oxadiazoles were efficiently synthesized in high yields by treatment of 1,3,4-oxadiazoles with aryl or alkenyl halides, respectively, in the presence of copper(II) oxide nanoparticles as a catalyst. The reusability of the catalyst is an important advantage in relation to practical applications of this synthesis. 2-Aryl- and 2-alkenyl-1,3,4-oxadiazoles were efficiently

  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.

  A series of novel 5-aryl-2-(2-arylethenyl)-1,3,4-oxadiazoles were synthesized by the 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) promoted oxidative cyclization of N′-(arylmethylidene)-3-arylacrylohydrazides. A facile and efficient one-pot protocol using the starting 3-arylacrylohydrazides and aromatic aldehydes is also reported. Short reaction times, high yields, a simple work-up procedure and the possibility

  通过2,3-二氯-5,6-二氰基苯并醌（DDQ）促进N '-（芳基亚甲基）的氧化环化反应合成了一系列新型的5-芳基-2-（2-芳基乙烯基）-1,3,4-恶二唑）-3-芳基丙烯酰肼。还报道了一种使用起始的3-芳基丙烯酰肼和芳族醛的简便有效的一锅操作方案。反应时间短，产率高，简单的后处理步骤以及氧化剂再生的可能性使所报道的方法成为合成2,5-二芳基-1,3,4-恶二唑的有前途的替代方法。
