Applications
(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.

Solubility
Solubility in hot Methanol, almost transparency.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from oxidizing agents.
