Prediction of tautomeric equilibri of hydroxypyridines by ab initio molecular orbital methods
Abstract
Ab initio calculations in a 3–21G basis, including a full geometry optimization in Cs symmetry, have been carried out for 2-,3-, and 4-hydroxypyridine and 2-, 3-, and 4-pyridone; values of ΔH° for the teutomeric equilibria, and the relative stabilities of the isomeric hydroxypyridines, are predicted to within 10kJ mol–1.
