Chloro(1,5-cyclooctadiene)rhodium(I) dimer(Cas 12092-47-6) Usage
| Description |
Chloro(1,5-cyclooctadiene)rhodium(I) dimer is primarily classified as an organometallic compound due to its rhodium-metal center and organic ligands. It is used widely as a precursor to homogeneous catalysts in various organic and inorganic chemical reactions. Chloro(1,5-cyclooctadiene)rhodium(I) dimer is an organometallic complex that consists of two rhodium atoms in the +1 oxidation state. Each rhodium atom is bonded to a chloride ion and a 1,5-cyclooctadiene (COD) ligand. The two rhodium atoms are bridged by chloride ions, forming a dimeric structure. This complex is highly valued for its role as a catalyst precursor in many chemical transformations, particularly in homogeneous catalysis. |
| Structure |
Dimeric complex with two rhodium centers bridged by chloride ions. The rhodium atoms are coordinated with 1,5-cyclooctadiene (COD) ligands. |
| Solubility |
Soluble in common organic solvents such as benzene, dichloromethane, and toluene. |
| Stability |
Stable under ambient conditions but may decompose upon exposure to moisture or light over time. |
| Uses |
Widely used in homogeneous catalysis, including reactions like hydrogenation, hydroformylation, and carbon-carbon bond formation. Chloro(1,5-cyclooctadiene)rhodium(I) dimer acts as a precursor for generating active rhodium species in situ, which can catalyze a variety of transformations. |
