CAS 100165-88-6: (S)-(-)-2,2'-Bis(di-p-tolylphosphino)-1,1'-binaphthyl

(S)-(-)-2,2'-Bis(di-p-tolylphosphino)-1,1'-binaphthyl is chiral ligand widely used in asymmetric synthesis. It also used as excellent catalysts for asymmetric hydrogenation of alkenes and some cyclic anhydrides. BINAP is used in organic synthesis for enantioselective transformations catalyzed by its complexes of ruthenium, rhodium, and palladium This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

(S)-(-)-2,2-Bis(di-p-Tolylphosphino)-1,1-Binaphthyl

(S)-2,2'-Bis[bis(4-methylphenyl)phosphino]-1,1'-binaphthyl is a phosphine ligand that is used in catalytic asymmetric synthesis. It is prepared by the reaction of 4-bromo-N,N-dimethylaniline with bis(dichlorodiphenylphosphino)methane and palladium tetrakis (triphenylphosphine). The ligand has been shown to be effective in the allylation of aldehydes and the asymmetric synthesis of organic compounds.
