Benzoylacetonates

Benzoylacetonates are a class of organic compounds that are derivatives of benzoylacetone. Benzoylacetone itself is a beta-diketone with the chemical formula C10H10O2. Benzoylacetonates are typically metal complexes where the benzoylacetonate anion acts as a chelating ligand. This anion is formed by the deprotonation of benzoylacetone, which readily undergoes keto-enol tautomerism. The resulting enolate form is stabilized by resonance and can coordinate to metal ions through its two oxygen atoms.

These metal benzoylacetonate complexes exhibit a variety of interesting properties and find applications in different fields. For example, they are used as catalysts in organic synthesis, particularly in polymerization reactions and as precursors for the deposition of metal oxide films through techniques like chemical vapor deposition. The specific properties of a benzoylacetonate complex, such as its solubility, stability, and reactivity, are highly dependent on the identity of the central metal ion. Transition metals, lanthanides, and actinides are commonly found in benzoylacetonate complexes. The synthesis of these compounds typically involves reacting a metal salt with benzoylacetone in the presence of a base. The resulting complexes can often be isolated as crystalline solids.
