Sodium acetylacetonate, Na(acac), is the precursor to many acetylacetonate complexes. A general method of synthesis is to treat a metal salt with acetylacetone in the presence of a base: [12] MB z + z Hacac ⇌ M(acac) z + z BH. Both oxygen atoms bind to the metal to form a six-membered chelate ring.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Sodium acetylacetonate is an organic compound with the nominal formula Na[CH(C(O)CH 3) 2]. This white, water-soluble solid is the conjugate base of acetylacetone . [ 1 ]
Rhodium acetylacetonate is the coordination complex with the formula Rh(C 5 H 7 O 2) 3, which is sometimes known as Rh(acac) 3. The molecule has D 3-symmetry. It is a yellow-orange solid that is soluble in organic solvents. It is prepared from RhCl 3 (H 2 O) 3 and acetylacetone. [1]
Vegetal detritus generally is not soluble in water and, therefore, is inaccessible to plants. It constitutes, nevertheless, the raw matter from which plant nutrients derive. Soil microbes decompose it through enzymatic biochemical processes, obtain the necessary energy from the same matter, and produce the mineral compounds that plant roots are ...
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 each.

Many such complexes are soluble in organic solvents, in contrast to the related metal halides. Because of these properties, acac complexes are sometimes used as catalyst precursors and reagents. Applications include their use as NMR "shift reagents" and as catalysts for organic synthesis , and precursors to industrial hydroformylation catalysts.
