OR:

Sodium acetylacetonate is an
organic compound Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-co ...
with the nominal formula Na H(C(O)CH3)2 This white, water-soluble solid is the conjugate base of
acetylacetone Acetylacetone is an organic compound with the chemical formula . It is classified as a 1,3-diketone. It exists in equilibrium with a tautomer . The mixture is a colorless liquid. These tautomers interconvert so rapidly under most conditions that ...
.


Preparation

The compound is prepared by deprotonation of acetylacetone: :NaOH + CH2(C(O)CH3)2 → NaCH(C(O)CH3)2 + H2O The anhydrous compound is produced by deprotonation with
sodium hydride Sodium hydride is the chemical compound with the empirical formula Na H. This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis. NaH is a saline (salt-like) hydride, composed of Na+ and H− ions, in co ...
in an aprotic solvent such as THF: :NaH + CH2(C(O)CH3)2 → NaCH(C(O)CH3)2 + H2


Reactions

Oxidation of the salt gives
tetraacetylethane Tetraacetylethane is the organic compound with the nominal formula H(C(O)CH3)2sub>2. It is a white solid that has attracted interest as a precursor to heterocycles and metal complexes. It is prepared by oxidation of sodium acetylacetonate: :I2 + ...
. With metal salts, it reacts to give metal acetylacetonate complexes. Alkylation of sodium acetylacetonate can result in both O-alkylation and C-alkylation. The former gives the enol ether and the latter gives 3-substituted derivative of acetylacetone.


Structure

The structure of the monohydrate has been established by
X-ray crystallography X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to Diffraction, diffract in specific directions. By measuring th ...
. The sodium cation is bonded to the enolate oxygen centers.
