Synthesis of alkyl (3-pyridyl)hydroxymethylphosphonates and their IR spectra
- 21 Downloads
The reaction of dialkyl H-phosphonates with pyridine-3-carbaldehyde gives alkyl (3-pyridyl)hydroxymethylphosphonates. In liquid systems, the hydrogen atom is localized at the oxygen atom of the hydroxyl group; in crystals, the existence of a zwitter-ionic form could not be excluded. In CHCl3 solutions, isolated molecules and cyclic dimeric H-complexes exist in an equilibrium.
