Description

1,1'-Bis(1-Diphenylphosphino-1-Methylethyl)Ferrocene is a specialized, chiral ferrocene-based diphosphine ligand, a key component in asymmetric catalysis. Its value lies in its ability to induce high enantioselectivity in transition metal-catalyzed reactions, enabling the production of optically pure compounds. This product is essential for researchers and process chemists in the pharmaceutical, agrochemical, and fine chemical industries who require precise stereochemical control for developing new active ingredients and advanced materials.

Application

• As a chiral ligand for asymmetric hydrogenation of olefins, ketones, and imines.
• Catalyst component in asymmetric C-C bond-forming reactions, including cross-coupling and allylic substitution.
• Key reagent for the synthesis of enantiomerically pure pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
• Use in the development of novel agrochemicals requiring specific stereochemistry for enhanced activity.
• Research and development of advanced materials and specialty chemicals with chiral properties.
• Catalyst screening and optimization in academic and industrial R&D laboratories.
