(R)-(-)-1,1'-Binaphthyl-2,2'-diyl hydrogen phosphate, 98+%
CAS: 39648-67-4 | C20H12O4P | 347.29 g/mol
Supplier: Thermo Scientific Chemicals L14149MD
Description
(R)-(-)-1,1'-Binaphthyl-2,2'-diyl hydrogen phosphate is 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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
