The Uses of (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

The Uses of (S)-(-)-2,2'-BIS(DI-P-TOLYLPHOSPHINO)-1,1'-BINAPHTHYL

(S)-T-BINAP reacts with silver nitrate to form (S)-Tol-BINAP·AgNO3, which can catalyze the enantioselective allylation reaction of aldehydes to form enantiopure secondary alcohols. It may be used as a chiral ligand in the palladium catalyzed asymmetric double carbohydroamination of iodoarenes to form α-aminoamides. It can also catalyze the asymmetric N-allylation reaction of ortho-tert-butylanilide derivatives with diallyl carbonate to form chiral N-allyl ortho-tert-butylanilides.
