Acid-catalyzed tautomerization is a chemical process in which a compound shifts between two structural forms, known as tautomers, with the assistance of an acid catalyst. This reaction typically involves the protonation of a carbonyl group, leading to the formation of an enol from a keto form and vice versa. This process is essential in understanding keto-enol tautomerism, as it illustrates how acids can facilitate the interconversion of these two important forms.
