Abstract

Tautomerism of 3-R-2,6-dihydroxy-4-methylpyridine, where R = CN, COOH, was studied by FTIR and UV, in both solid state and different solvents. It was found that the hydroxypyridonic form is the predominant tautomer in most cases, while the interaction with solvents has a limited influence upon the nature and ratio of the other existing tautomers.
