A Derivative of 1,3,4-Oxadiazole

Acta Crystallographica Section C Crystal Structure Communications, 1995
The molecules of title compound, 2-(4-chloroanilino)-5-(4-pyridyl)-1,3,4-oxadiazole, C 13 H 9 ClN 4 O, are nearly planar with a maximum deviation of 0.094 (2) A from the plane. Intermolecular N(1)-H...N(4') hydrogen bonds link the molecules into chains [N(1)...N(4')= 2.902 (3) A, N(1)-H...N(4')=178 (2)°].

Novel syntheses of symmetrical 2,5-diaryl-1,3,4-oxadiazoles and 1,4-phenylenebis-1,3,4-oxadiazoles

Russian Chemical Bulletin, 1998
The reactions of trichloromethylarenes with excess hydrazine hydrate in ethanol gives symmetrical 2,5-diaryl-1,3,4-oxadiazoles in 68–96% yields. The reaction of 1,4-bis(trichloromethyl)benzene with acylhydrazines in an ethanol-pyridine mixture gives the corresponding substituted or unsubstituted 1,4-phenylenebis-1,3,4-oxadiazoles in 35–51% yields.
