Description

Chiral catalyst ligand | CAS: 100165-88-6 | C48H40P2 | 678.796 g/mol

(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
