The field of asymmetric catalysis relies heavily on the sophisticated design and application of chiral ligands that can precisely control the stereochemical outcome of chemical reactions. One such ligand, (S)-(-)-2,2'-Bis(di-p-Tolylphosphino)-1,1'-Binaphthyl, identified by CAS number 100165-88-6 and widely known as (S)-(-)-TolBINAP, is a cornerstone in modern organic synthesis. As a dedicated chemical manufacturer and supplier based in China, we are proud to offer this high-quality material, essential for achieving excellent results in your chemical research and production.

The chemical structure of (S)-(-)-TolBINAP is central to its function as a powerful chiral ligand. It features a rigid 1,1'-binaphthyl backbone that creates a specific chiral environment. Attached to this backbone are two di-p-tolylphosphino groups, which are Lewis basic and readily coordinate to transition metals like palladium, rhodium, and copper. This coordination forms highly active and stereoselective catalytic species. The (S) enantiomer, specifically, is crucial for directing reactions towards desired chiral products, making it a sought-after reagent for synthesizing enantiomerically pure compounds, particularly in the pharmaceutical and fine chemical industries.

Understanding the applications of (S)-(-)-TolBINAP reveals its broad utility. It is frequently employed in palladium-catalyzed cross-coupling reactions, such as the Heck reaction and the Suzuki coupling, where it promotes high yields and enantioselectivity. Furthermore, it has shown significant efficacy in Cu-catalyzed asymmetric conjugate additions and Rh-catalyzed cycloadditions.
