Chloro(1,5-cyclooctadiene)rhodium(I) dimer(CAT: R019805), often written as [RhCl(COD)]₂, is a bright yellow, air-stable organometallic complex widely used as a catalyst precursor in homogeneous catalysis and organic synthesis. Each rhodium(I) center is coordinated to a 1,5-cyclooctadiene (COD) ligand and bridged by two chloride ligands, forming a dimeric structure. It serves as a versatile starting material for generating rhodium catalysts used in hydrogenation, hydroformylation, carbon–carbon coupling, and asymmetric transformations. Its good solubility in organic solvents and relative stability under ambient conditions make it practical for laboratory and industrial applications.
