Bis(1,5-cyclooctadiene)diiridium(I) dichloride
Bis(1,5-cyclooctadiene)diiridium(I) dichloride (CAS 12112-67-3) is an organoiridium(I) coordination complex with the empirical formula C16H24Cl2Ir2 and a molecular weight of 671.70 g/mol. Commonly written as [Ir(cod)Cl]2, it is a chloride-bridged dimer in which each iridium(I) centre carries a chelating 1,5-cyclooctadiene ligand. It serves chiefly as an iridium precursor and catalyst component in homogeneous catalysis and organometallic synthesis. Tech Serve Solutions supplies it as a research-grade reagent at 97% assay to laboratory and industrial customers worldwide.

Precursor for asymmetric allylic substitution
Acts as a metal precursor in iridium-catalysed asymmetric allylic substitution reactions. The cyclooctadiene ligands are readily displaced, generating active iridium species when combined with chiral ligands.
Iridium source in homogeneous catalysis
Widely used as a convenient, soluble Ir(I) starting material for preparing catalysts. The labile COD ligands and bridging chlorides allow ready entry to a range of iridium phosphine, carbene and related complexes.
Organometallic and coordination synthesis
Employed in research laboratories to construct defined iridium complexes for ligand-exchange studies and mechanistic investigations in organometallic chemistry.
Catalyst development and reaction screening
Used as a standard iridium component when screening ligand and substrate combinations during the development of new homogeneous catalytic systems.
