Rhodium(III) 2,4-pentanedionate is used in catalytic reagents for organic synthesis. Rhodium(III) 2,4-pentanedionate is useful for hydrosilylation of a variety of organic substrates like alkenes, terminal or internal acetylenes, conjugated dienes, alpha, beta -unsaturated aldehydes and allylic compounds. It performs the role of a catalyst in well-known reactions such as transformation processes including hydrogenation, ethanol steam reforming, CO oxidation, and NOx reduction. Rhodium acetylacetonate, as the organic solvent-soluble source of rhodium metal ions, can be used to prepare monodisperse size/shape controlled Rh nanocrystals. Rh nanocrystal monolayers have been reported to show high activity for hydrogenation of vinylcyclohexene to selectively produce ethylcyclohexene. The size/shape controlled nanocrystals find a variety of applications in oil refining processes, chemical synthesis and fuel cell technology.


Rhodium(III) 2,4-pentanedionate is stable under normal conditions of storage and use.
