Usage

Description

Rhodium(III) 2,4-pentanedionate, also known as Rhodium acetylacetonate, is a chemical compound with the formula Rh(acac)3. It is a yellow/orange crystalline solid that serves as an important catalyst in various chemical reactions and processes.

Uses

Used in Organic Synthesis:
Rhodium(III) 2,4-pentanedionate is used as a catalytic reagent for organic synthesis, particularly for hydrosilylation of a variety of organic substrates such as alkenes, terminal or internal acetylenes, conjugated dienes, alpha, beta-unsaturated aldehydes, and allylic compounds. It plays a crucial role as a catalyst in well-known reactions, including transformation processes like hydrogenation, ethanol steam reforming, CO oxidation, and NOx reduction.
Used in Nanocrystal Preparation:
Rhodium acetylacetonate, as an organic solvent-soluble source of rhodium metal ions, is used to prepare monodisperse size/shape controlled Rh nanocrystals. These nanocrystals have been reported to exhibit high activity for hydrogenation of vinylcyclohexene to selectively produce ethylcyclohexene. The size/shape controlled nanocrystals find a variety of applications in industries such as oil refining, chemical synthesis, and fuel cell technology.
Used in Hydrogenation of Carboxylic Acids:
Rhodium(III) 2,4-pentanedionate is also an effective catalyst for the hydrogenation of carboxylic acids when combined with group 6 or group 7 metal carbonyls. This application further expands its utility in the chemical industry for the production of various chemicals and materials.
