Abstract
Abstract Treating 2-aminopyridine with pyridine-3-carboxaldehyde, pyridine-4-carboxaldehyde and benzaldehyde, and 3-aminopyridine with pyridine-4-carboxaldehyde leads to the formation of the corresponding aminal instead of the expected Schiff base. The IR and 1H NMR spectra of these compounds are described and discussed. Also, the X-ray data of the compound 3-pyridyl-N,N-di(2-pyridylamino)-methane is described and discussed. Infrared, 1H NMR and crystal data indicate that these aminals enjoy intermolecular hydrogen bonding. This effect is considered to contribute significantly to their unusual stability.
