ketoenoltautomerie
Ketoenoltautomerie refers to the reversible isomerization of a chemical compound between its keto (carbonyl-containing) and enol (hydroxyl-containing) forms. This phenomenon is a fundamental concept in organic chemistry, particularly in the study of carbonyl compounds such as aldehydes, ketones, and β-dicarbonyl compounds. The equilibrium between these two tautomers is typically favored toward the keto form due to its greater thermodynamic stability, though certain conditions can shift the balance toward the enol form.
The process involves the migration of a proton (H⁺) and the rearrangement of double bonds. In the
Ketoenoltautomerie plays a crucial role in various biochemical processes, including enzymatic reactions and metabolic pathways. For
