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...

compound with the
formula VO(acac)2,
where acac– is the
conjugate base of
acetylacetone. It is a blue-green

colorless liquid is
significant commercially as the prin****l
precursor to
acetylacetone. In
organic synthesis, it is used to
prepare enol
acetates of ketones...

- water-soluble
solid is the
conjugate base of
acetylacetone. The
compound is
prepared by
deprotonation of
acetylacetone: NaOH + CH2(C(O)CH3)2 → NaCH(C(O)CH3)2...

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

tautomerization typically strongly favors the keto tautomer, but an
important exception is the case of 1,3-****tones such as
acetylacetone....
