A convenient, efficient and one-pot synthesis of chemically and pharmaceutically interesting symmetrical-2,5-disubstituted-1,3,4-oxadiazoles is reported. The protocol involves anodic oxidation of aldehyde-N-arylhydrazones in anhyd. MeCN-LiClO4. Constant potential electrolysis carried out in an undivided cell and platinum electrodes leads to the formation of the corresponding oxadiazoles under ambient condition and the mechanism was deduced from voltammetry studies. The reaction proceeded smoothly with high atom economy. Springer Science+Business Media Dordrecht 2013.

Symmetrically substituted 2,5-diaryl-1,3,4-oxadiazoles have been prepared in 81-92% yields by a new direct one-pot synthesis from arenecarboxylic acids, hydrazine dihydrochloride, anhydrous phosphoric acid and sodium borohydride in the absence of a solvent at 170-180°C for 5-6h.

Various 1,3,4-oxadiazoles have been synthesized in excellent yields by BF3·Et2O promoted cyclodehydration of 1,2-diacyl and diaroyl hydrazines prepared in situ from corresponding acid chlorides and hydrazine.
