Acetylacetone is an
organic compound with the
chemical formula CH3−C(=O)−CH2−C(=O)−CH3. It is
classified as a 1,3-****tone. It
exists in
equilibrium with...

acetaldehyde (K = [enol]/[keto] ≈ 3×10−7). In 1,3-****tones, such as
acetylacetone (2,4-pentanedione), the enol form is more favored. The acid-catalyzed...
