Bis(1,5-cyclooctadiene)dirhodium(I) dichloride
Bis(1,5-cyclooctadiene)dirhodium(I) dichloride (CAS 12092-47-6), formula C16H24Cl2Rh2 and molar mass 493.08 g/mol, is an organorhodium(I) coordination complex commonly written as [RhCl(COD)]2. This air-stable chloro-bridged dimer, in which each rhodium centre carries a 1,5-cyclooctadiene ligand, is a widely used precatalyst and starting material in homogeneous catalysis and organometallic synthesis. Tech Serve Solutions supplies it as a research-grade reagent (assay 98%) to laboratories and process chemists worldwide.

Homogeneous catalysis precatalyst
Serves as a convenient rhodium(I) source for homogeneous catalytic systems. The labile cyclooctadiene ligands are readily displaced, generating active rhodium species in solution.
Precursor to phosphine and chiral rhodium complexes
Reacts with phosphine, diphosphine and other donor ligands to form defined Rh(I) catalysts. It is a standard entry point for preparing complexes used in asymmetric catalysis research.
Hydrogenation and related reductions
Used to generate rhodium catalysts for the hydrogenation of alkenes and other unsaturated substrates under laboratory conditions. Performance depends on the supporting ligands chosen by the user.
Organometallic and methodology research
Employed in academic and industrial method development for carbon-carbon and carbon-heteroatom bond formation, including 1,4-additions and various rhodium-catalysed transformations.
Catalyst and materials development
Acts as a soluble molecular rhodium source for screening, ligand evaluation and supported-catalyst studies in chemical synthesis programmes.
