Sodium acetylacetonate is an organic compound with the nominal formula Na[CH(C(O)CH3)2].

This white, water-soluble solid is the conjugate base of acetylacetone.

[1] The compound is prepared by deprotonation of acetylacetone: [2] The anhydrous compound is produced by deprotonation with sodium hydride in an aprotic solvent such as THF:[3] Oxidation of the salt gives tetraacetylethane.

Alkylation of sodium acetylacetonate can result in both O-alkylation and C-alkylation.

The sodium cation is bonded to the enolate oxygen centers.
