2-(4'-Acetylbiphenyl-4-yl)-5-phenyl-1,3,4-oxadiazole (I) was converted into α,β-unsaturated ketone II and pyridinium salt IV, which were used in preparation of triarylpyridines XIII-XIX by Kröhnke's method. Also the diketones V-VIII were obtained from derivative I and served as precursors for the synthesis of pyrazoles IX-XII. The discussion of 1H NMR spectra and luminescent properties of prepared bifluorophoric heterocyclic systems is given.
