Description

Racemic-2,2Bis(Diphenylphosphino)-1,1Binaphthyl CAS NO 78327-87-8 is a high-purity, atropisomeric bidentate phosphine ligand essential for advanced catalytic processes. Its primary value lies in its ability to act as a versatile chiral or achiral scaffold in transition metal catalysis, enabling precise control over reaction stereochemistry and yield. This compound is critically needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries for developing and scaling up asymmetric synthesis, including hydrogenation and cross-coupling reactions.

Application

• As a key ligand in asymmetric hydrogenation reactions for the synthesis of chiral pharmaceutical intermediates.
• As a catalyst component in cross-coupling reactions (e.g., Suzuki, Heck) for constructing complex organic molecules.
• In homogeneous catalysis research for developing new synthetic methodologies.
• For the preparation of transition metal complexes used in academic and industrial research.
• As a chiral auxiliary or resolving agent in stereoselective synthesis.
• In the development of advanced materials and organometallic compounds.
