This rhodium(I) complex is used as a homogeneous catalyst precursor in organic synthesis, particularly in hydrogenation reactions. When combined with chiral ligands, it enables high enantioselectivity in the asymmetric reduction of prochiral alkenes, imines, and ketones, making it valuable for producing chiral intermediates in pharmaceuticals and fine chemicals. The phosphine ligand framework (dppb) enhances stability and selectivity, supporting efficient performance under mild conditions. It is commonly employed in academic and industrial research for synthesizing enantiopure compounds.
