  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 .

  4. Metal acetylacetonates - Wikipedia

    en.wikipedia.org/wiki/Metal_acetylacetonates

    Metal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH 3 COCHCOCH − 3) and metal ions, usually transition metals. The bidentate ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring.

  5. Acetone - Wikipedia

    en.wikipedia.org/wiki/Acetone

    Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.

    en.wikipedia.org/wiki/VOC_exempt_solvent

    In the US, dimethyl carbonate was exempted under the definition of volatile organic compounds (VOCs) by the U.S. EPA in 2009. [9] Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents.

  9. 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.
