Used as a highly selective homogeneous catalyst in hydroformylation reactions, particularly for converting alkenes into aldehydes with high regioselectivity. It enables efficient addition of syngas (CO and H₂) across double bonds under mild conditions. The catalyst is especially effective for terminal alkenes, promoting linear aldehyde formation, which is valuable in producing plasticizers, detergents, and fine chemicals. Its phosphinite and phosphinous acid ligands enhance stability and catalytic activity, allowing for lower reaction pressures and improved turnover numbers compared to traditional catalysts.
