Product No.:SRCHEM0003
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

Structural Formula:



Molecular Formula: C20H13O4P
Molecular Weight: 348.29
CAS Number: 39648-67-4
Beilstein Registry Number: 4713363
PubChem Substance ID: 24854961

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. Used in a chiral Bronsted acid catalyzed enantoselective Mannich reaction.
