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

continuous flow process is reported for the synthesis of various 1,3,4-oxadiazoles via an iodine-mediated oxidative cyclisation approach. This entails the use of a heated packed-bed reactor filled with solid K2CO3 as a base. Using DMSO as solvent, this flow method generates the target heterocycles within short residence times of 10 minutes and in yields up to 93%. Scale-up of this flow process was
