| Abstract: | A convenient method to synthesize three 2,5-diaryl-1,3,4-oxadiazoles via the intramolecular cyclodehydration of diacylhydrazide intermediates which were prepared from the condensation of carboxylic acids with hydrazides in the presence of POCl3 was reported.The corresponding physical properties were characterized by IR and 1HNMR spectra respectively.Fluorescent results indicate that the target compounds have high fluorescence quantum yields and large Stokes shifts. |
