4-Pyridone is an
organic compound with the formula C
5H
4NH(O). It is a colorless solid.
4-Pyridone, and its derivatives, are prepared from 4-pyrone and amines in protic solvents. [1] [2] [3]
4-Pyridone exists a keto-enol tautomerism with its enol tautomer 4-hydroxypyridine. In solution, the keto tautomer is favoured, [4] and the enol tautomer only becomes important in very dilute solutions or solutions of non-polar solvents. However, the enol tautomer is dominant in the gas phase. [5]
Fluridone is an aquatic herbicide that contains a 4-pyridone subunit. [6]
