说明

一般描述

Pyridine (Pyr) is a nitrogen containing six membered heterocyclic compound commonly used as a base. It is a colorless liquid with a fishy odor. Pyridine moiety is present as a major component in a number of compounds like pyridine nucleotides,[1] pyridine alkaloids,[2] pyridine-based polymers[3] and pyridine-containing macrocycles.[4] It has wide application as a solvent, catalyst and as an intermediate for synthesis.[5] IR, Raman and UV spectra of pyridine have been analyzed and the values obtained were used to calculate its thermodynamic properties.[6] Photodegradation[7] and bacterial degradation of Pyr has been studied.[8]
 

应用

Pyridine may be used in the synthesis of the following:
  • complexes with cobalt(II) halides[9]
  • pyridine-5, a deuterated form of pyridine[10]
  • ionic liquid matrices (ILMs)[11]
