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.
2-(4'-乙酰基联苯基)-5-苯基-1,3,4-噁二唑(I)被转化为α,β-不饱和酮II和吡啶盐IV,这些化合物通过Kröhnke方法用于制备三芳基吡啶XIII-XIX。另外,从衍生物I获得的二酮V-VIII可作为合成嘧啶IX-XII的前体。对制备的双氟光异构杂环系统的1H NMR光谱和发光性能进行了讨论。
