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 ...
Variations of acetylacetonate have also been developed with myriad substituents in place of methyl (RCOCHCOR ′ −). [1] 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.
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]
Aluminium acetylacetonate, also referred to as Al(acac) 3, is a coordination complex with formula Al(C 5 H 7 O 2) 3. This aluminium complex with three acetylacetone ligands is used in research on Al-containing materials.
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.
Thus ethyl acetoacetate behaves similarly to acetylacetone: [6] CH 3 C(O)CH 2 CO 2 C 2 H 5 + NaH → CH 3 C(O)CHNaCO 2 C 2 H 5 + H 2. The resulting carbanion undergoes nucleophilic substitution. Ethyl acetoacetate is often used in the acetoacetic ester synthesis, comparable to diethyl malonate in the malonic ester synthesis or the Knoevenagel ...
Chromium(III) acetylacetonate is the coordination compound with the formula Cr(C 5 H 7 O 2) 3, sometimes designated as Cr(acac) 3. This purplish coordination complex is used in NMR spectroscopy as a relaxation agent because of its solubility in nonpolar organic solvents and its paramagnetism .
Indium acetylacetonate and tin(II) acetylacetonate can be used to prepare indium tin oxide thin films with an atmospheric‐pressure chemical vapor deposition method. The resulting thin films are transparent and conductive, with a thickness of about 200 nanometers. [3]
