Organophosphorus Compounds

Diphosphines, sometimes called bisphosphanes, are organophosphorus compounds used as ligands in inorganic and organometallic chemistry. They are identified by the presence of two phosphino groups linked by a backbone, and are usually chelating.

Introduction of (S)-(-)-2,2”-Bis(diphenylphosphino)-1,1”-binaphthyl CAS NO.76189-56-5

The development of efficient chiral phosphorus ligands has played an important role in the development of asymmetric hydrogenation. Today, thousands of efficient chiral phosphorus

ligands with diverse structures have been developed, and their applications in asymmetric hydrogenation have been extensively utilized in both academic research and industry. The development of many efficient chiral phosphorus ligands also allows the discovery of new mechanistic information of Rh- or Ru-catalyzed asymmetric hydrogenation. The catalysts

are not restricted on those with Rh or Ru metals; complexes of other transition metals such as

Ir, Pt, Ti, Zr, and Pd are also effective. Numerous unsaturated compounds can be hydrogenated in

excellent ee’s using a metal catalyst associated with an appropriate chiral ligand.
