Widely used as a catalyst precursor in homogeneous catalysis, especially in reactions involving C–H activation and conjugate addition. It shows high efficiency in asymmetric synthesis when paired with chiral ligands, enabling the production of enantiomerically enriched compounds important in pharmaceuticals and fine chemicals. Commonly employed in rhodium-catalyzed cyclization and coupling reactions due to its ability to form active rhodium(I) species under mild conditions. Its dimeric structure provides stability while remaining reactive upon ligand exchange, making it ideal for controlled catalytic processes.
