Applications

(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

Notes

Store away from strong oxidizing agents. Keep container tightly closed. Store in cool, dry conditions in well sealed containers.
