Abstract

The H-1 and C-13 NMR spectra, molecular conformation and intermolecular association of N-(2-pyridinyl)-2-pyridinecarboxamides and 2-pyridinecarboxamide are discussed. The H-1 NMR spectra have been analyzed with the aid of COSY spectra and the C-13 spectra with the aid of HETCOR, proton coupled spectra and C-13-H-1 coupling constants. In concentrated CDCl3 solution, N-(2-pyridinyl)-2-pyridinecarboxamides dimerise by intermolecular association.
