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...
- In enzymology, an
acetylacetone-cleaving
enzyme (EC 1.13.11.50) is an
enzyme that
catalyzes the
chemical reaction pentane-2,4-dione + O2 ⇌ {\displaystyle...

compound with the
formula VO(acac)2,
where acac– is the
conjugate base of
acetylacetone. It is a blue-green
solid that
dissolves in
polar organic solvents....

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

acidic proton in the enol
tautomer of
acetylacetone appears at δ H {\displaystyle \delta _{\text{H}}} 15.5,

diacetyl (CH3C(O)C(O)CH3), once used as butter-flavoring in popcorn.
Acetylacetone (pentane-2,4-dione) is
virtually a
misnomer (inappropriate name) because...

moderately acidic. Thus
ethyl acetoacetate behaves similarly to
acetylacetone: CH3C(O)CH2CO2C2H5 + NaH → CH3C(O)CHNaCO2C2H5 + H2 The
resulting carbanion...

fused to a
benzene ring.
