  2. Acetylacetone - Wikipedia

    en.wikipedia.org/wiki/Acetylacetone

    Acetylacetone is a versatile bifunctional precursor to heterocycles because both keto groups may undergo condensation. For example, condensation with hydrazine produces pyrazoles while condensation with urea provides pyrimidines .

  3. Metal acetylacetonates - Wikipedia

    en.wikipedia.org/wiki/Metal_acetylacetonates

    The usual synthesis involves treatment of a metal salt with acetylacetone, acacH: [2] M z+ + z Hacac ⇌ M(acac) z + z H + Addition of base assists the removal of a proton from acetylacetone and shifts the equilibrium in favour of the complex. Both oxygen centres bind to the metal to form a six-membered chelate ring.

  4. Tris(acetylacetonato)iron(III) - Wikipedia

    en.wikipedia.org/wiki/Tris(acetylacetonato)iron(III)

    Tris(acetylacetonato) iron(III), often abbreviated Fe(acac) 3, is a ferric coordination complex featuring acetylacetonate (acac) ligands, making it one of a family of metal acetylacetonates. It is a red air-stable solid that dissolves in nonpolar organic solvents.

    en.wikipedia.org/wiki/Acetylation

    Salicylic acid is acetylated to form aspirin. In chemistry, acetylation is an organic esterification reaction with acetic acid.It introduces an acetyl group into a chemical compound.

  6. Vanadyl acetylacetonate - Wikipedia

    en.wikipedia.org/wiki/Vanadyl_acetylacetonate

    Vanadyl acetylacetonate is the chemical 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. The coordination complex consists of the vanadyl group, VO 2+, bound to two acac – ligands via the two oxygen atoms on each.

  7. Enol - Wikipedia

    en.wikipedia.org/wiki/Enol

    In 1,3-diketones, such as acetylacetone (2,4-pentanedione), the enol form is favored. The acid-catalyzed conversion of an enol to the keto form proceeds by proton transfer from O to carbon. The process does not occur intramolecularly, but requires participation of solvent or other mediators.
