Description

(R)-(+)-2,2'-Bis(Dicyclohexylphosphino)-1,1'-Binaphthyl is a high-value, chiral bidentate phosphine ligand, widely recognized in the chemical industry for its exceptional ability to induce enantioselectivity in catalytic transformations. Its primary value lies in enabling the production of single-enantiomer compounds, which is critical for the efficacy and safety of many pharmaceuticals and advanced materials. This ligand is essential for research and manufacturing chemists in the pharmaceutical, agrochemical, and fine chemical sectors who require precise stereochemical control in asymmetric hydrogenation, cross-coupling, and other transition metal-catalyzed reactions.

Application

• As a key chiral ligand in asymmetric hydrogenation reactions for the synthesis of enantiomerically pure pharmaceutical intermediates.
• Catalyst component for asymmetric cross-coupling reactions (e.g., Suzuki-Miyaura, Heck) to construct chiral biaryl structures.
• Enantioselective synthesis of active pharmaceutical ingredients (APIs) and natural products.
• Production of chiral agrochemicals and flavors & fragrances.
• Fundamental research and development in homogeneous catalysis and organometallic chemistry.
• Manufacturing of advanced materials and liquid crystals with specific chiral properties.
