Application
Rhodium(II) acetate dimer is an emerald green powder known for its high solubility in methanol and moderate solubility in water, surpassing the solubility of copper acetate. It serves primarily as a robust catalyst in various chemical processes. Notably, it catalyzes the formation of ylides and facilitates cyclopropanation of alkenes, oxidation of alcohols, and cyclization reactions involving diazo carbonyl groups. Additionally, this compound specializes in insertion into C-H and X-H bonds, where X can be NH, SH, or OH, and is effective in differentiating between ribonucleosides and deoxynucleosides. It also plays a crucial role in functionalizing fullerenes into polymers and efficiently catalyzes hydrogen transfer from 2-propanol to cyclohexanone and other unsaturated compounds. The dimer's catalytic utility extends to a wide range of reactions including the Doyle-Kirmse reaction, Claisen rearrangement, and the synthesis of aziridines from allylic N-tosyloxycarbamates. Furthermore, it supports Rh/NHC-catalyzed direct intermolecular arylation of C-H bonds and chiral Brønsted acid-Rh catalyzed three-component reactions involving diazo compounds with alcohols and imines. Its applications also cover Rh-catalyzed cyclopropenations of ynamides and tandem asymmetric aza-Darzens/ring-opening reactions. Additionally, Rhodium(II) acetate dimer is employed in synthesizing molybdenum triisopropylbenzoate isonicotinate, a compound noted for its ambivalent properties.
