[Study on the spectroscopy of 5-(4-pyridyl)-1,3,4-oxadiazole-2-thiol].
The title compound (5-(4-pyridyl)-1,3,4-oxadiazole-2-thiol) was synthesized by the ring-closing reaction of isoniazide with carbon bisulfide, and the reaction course was discussed preliminarily. The mechanism of this reaction is nucleophilic addition. The compound was characterized by Fourier transform infrared (FTIR) spectrometry and nuclear magnetic resonance (NMR). The thermal analytical data indicate that the compound was decomposed completely at the temperature of 506 degrees C.
