Product No.: 3C0022 Description: (R)-(-)-1,1'-Binaphthalene-2,2'-diyl hydrogen phosphate Synonyms: (R)-4-Hydroxydinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-oxide (R)-(-)-BNP ACID Molecular Formula: C20H13O4P Molecular Weight: 348.29 CAS Number: 39648-67-4 Beilstein Registry Number: 4713363 Application: A chiral ligand used in hydrocarboxylation reactions. Complexes with rhodium and mediates the asymmetric dipolar cycloaddition of diazo compounds. A number of racemic amines which have proven difficult to separate have been resolved with this chiral acid. Palladium derivatives have been used in asymmetric hydrocarboxylations, and rhodium derivatives have been used in dipolar cycloadditions.
