The spectroscopic (ir, uv, nmr, and ms) and thermal properties of N-(4-methyl-2-pyridyl)benzaldimine, N-(6-methyl-2-pyridyl)benzaldimine, N-(4-methyl-2-pyridyl)salicylaldimine and N-(6-methyl-2-pyridyl)salicylaldimine have been studied. Their acidity constants are discussed in relationship to their stereochemistry. Finally, reaction of these compounds with metal salts has been studied in a qualitative manner.
