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
Acetylacetone is an organic compound with the chemical formula CH 3 −C(=O)−CH 2 −C(=O)−CH 3.It is classified as a 1,3-diketone.It exists in equilibrium with a tautomer CH 3 −C(=O)−CH=C(−OH)−CH 3.
In 1,3-diketones, such as acetylacetone (2,4-pentanedione), the enol form is more 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.
2,3,4-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.
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. It is not stable at room temperature as a pure material, which has further ...
Methylene-interrupted polyenes are 1,4-pentadiene groups found in polyunsaturated fatty acids linoleic acid, α-linolenic acid, and arachidonic acid.These pentadiene derivatives are susceptible to lipid peroxidation, far moreso than monounsaturated or saturated fatty acids.
