Abstract

An efficient acid-catalyzed condensation between substituted benzohydrazides and 2,3,5,6-tetrafluoroterephthalic acid to form 1,4-bis(5-aryl-1,3,4-oxadiazol-2-yl)-2,3,5,6-tetrafluorobenzenes is reported. The products were isolated in 74–87% yield and were characterized by 1H NMR, IR, and mass spectra.
