It forms the acetylacetonate anion C 5 H 7 O − 2 (commonly abbreviated acac −): C 5 H 8 O 2 ⇌ C 5 H 7 O − 2 + H + The structure of the acetylacetonate anion (acac −) In the acetylacetonate anion, both C-O bonds are equivalent. Both C-C central bonds are equivalent as well, with one hydrogen atom bonded to the central carbon atom (the ...

Acetylpropionyl, also known as acetyl propionyl or 2,3-pentanedione, [1] is an organic compound, specifically a diketone. [2] Uses for acetylpropionyl include as a: Solvent for cellulose acetate, paints, inks, and lacquers; Starting material for dyes, pesticides, and drugs
2,3,4-Pentanetrione can be made by oxidizing 2,4-pentanedione with selenium dioxide. [2] Ludwig Wolff made the 2,3 oxime by reacting hydroxylamine with isonitrosoacetylacetone in cold, aqueous, concentrated solution. [3] Yet other ways to make triones start from a β-dione, and oxidise the carbon at the α position, between the two ketone groups.
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.
2-Methyl-2,4-pentanediol (MPD) is an organic compound with the formula (CH 3) 2 C(OH)CH 2 CH(OH)CH 3. This colourless liquid is a chiral diol . It is produced industrially from diacetone alcohol by hydrogenation . [ 4 ]
4,5-Dihydroxy-2,3-pentanedione (DPD) is an organic compound that occurs naturally but exists as several related structures. The idealized formula for this species is CH 3 C(O)C(O)CH(OH)CH 2 OH, but it is known to exist as several other forms resulting from cyclization.
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
