일반 설명

Pyridine is a basic N-heterocyclic compound. It acts as nitrogen donor ligand and forms many metal-pyridine complexes. Its complexes having tetrahedral and octahedral geometries can be differentiated by infra-red spectral investigations.

애플리케이션

Pyridine (py) may be used in the preparation of vanadium oxide nanoparticles and iron benzenedicarboxylates, Fe(OH)(BDC)(py)0.85 (BDC = 1,4-benzenedicarboxylate, py = pyridine). It may be employed as catalyst in Knoevenagel condensation reaction.
Pyridine may be used as a base for the conversion of:
  • Alkyltrichlorosilanes to trimethoxyalkylsilanes, which are used as precursors for preparing alkylsilicates.
  • 1-Indanone to 1-indanone oxime, which can undergo reductive ring-expansion to form tetrahydroquinoline.

It may also be used to catalyze the borylation reaction of haloarenes to form arylboronates without using transition metal catalysts.
