Acetylacetone is an organic compound with the chemical formula CH3−C (=O)−CH2−C (=O)−CH3. It is classified as a 1,3- diketone. It exists in equilibrium with a tautomer CH3−C (=O)−CH=C (−OH)−CH3. The mixture is a colorless liquid.

Acetylacetone is a beta-diketone that is pentane in which the hydrogens at positions 2 and 4 are replaced by oxo groups. It is a conjugate acid of an acetylacetonate. Acetylacetone has been reported in Nicotiana tabacum and Mangifera indica with data available. pentane-2,4-dione. Computed by Lexichem TK 2.7.0 (PubChem release 2021.10.14)

The bidentate ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring. The simplest complexes have the formula M(acac) 3 and M(acac) 2. Mixed-ligand complexes, e.g. VO(acac) 2, are also numerous.

2023年6月30日 · Acetylacetonate (acac-, top) is an anionic bidentate ligand that coordinates metal ions through two oxygen atoms. Acac-is a hard base so it prefers hard acid cations. With divalent metal ions, acac-forms neutral, volatile complexes such as Cu(acac) 2 and Mo(acac) 2 that are useful for chemical vapor deposition (CVD) of metal thin films.

Acetylacetone is an organic compound with molecular formula C 5 H 8 O 2. This diketone is formally named 2,4-pentanedione, although as discussed below, this name does not properly describe the predominant structure, as it is a vinylogous carboxylic acid.

2021年9月28日 · Acetylacetonate (acac-, right) is an anionic bidentate ligand that coordinates metal ions through two oxygen atoms. Acac-is a hard base so it prefers hard acid cations. With divalent metal ions, acac-forms neutral, volatile complexes such as Cu(acac) 2 and Mo(acac) 2 that are useful for chemical vapor deposition (CVD) of metal thin films.

ACAC is typically used in excess to accelerate the rate of enzymatic catalysis. A molar ratio of [CTA]:[HRP]:[H 2 O 2]:[ACAC] being 1:0.00054:0.2:4 was reported for the RAFT syntheses to afford well-defined polymers with a high polymerization rate and a …

2017年12月30日 · Metal acetylacetonates are coordination complexes derived from the acetylacetonate anion and metal ions, usually transition metals. The ligand acetylacetonate is a β -diketone often abbreviated as “acac”. Acetylacetone is an organic compound that famously exists in two tautomeric forms which are rapidly inter-convertible.

2021年12月31日 · Acetylacetone is an organic compound with the chemical formula CH3COCH2COCH3. The compound exists in equilibrium with a tautomer CH 3 C (O)CH= (OH)CH 3. These tautomers interconvert so rapidly under most conditions that they are treated as a single compound in most applications. The keto …
