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
Some molecular compounds that adopt square pyramidal geometry are XeOF 4, [2] and various halogen pentafluorides (XF 5, where X = Cl, Br, I). [ 3 ] [ 4 ] Complexes of vanadium (IV), such as vanadyl acetylacetonate , [VO(acac) 2 ], are square pyramidal (acac = acetylacetonate, the deprotonated anion of acetylacetone (2,4-pentanedione)).

Levi and Zanetti extended the Knorr synthesis in 1894 to the use of acetylacetone (2,4-pentanedione) in reaction with ethyl 2-oximinoacetoacetate. The result was ethyl 4-acetyl-3,5-dimethylpyrrole-2-carboxylate, where "OEt" = R 1 = R 3 = Me, and R 2 = COOEt. [9] The 4-acetyl group could easily be converted to a 4-ethyl group by Wolff-Kishner ...
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.
As a result, its pK aH is 13.6 [2] (pK b of 0.4) meaning that guanidine is a very strong base in water; in neutral water, it exists almost exclusively as guanidinium. Due to this, most guanidine derivatives are salts containing the conjugate acid.

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 ...
