(S)-BINAP is the enantiomeric counterpart of (R)-BINAP, a privileged chiral diphosphine ligand developed by Noyori. It forms highly enantioselective complexes with ruthenium, rhodium, and palladium for asymmetric hydrogenation, allylic substitution, and cross-coupling reactions.
Applications
- Asymmetric hydrogenation with Ru and Rh
- Enantioselective allylic alkylation with Pd
- Asymmetric Heck reactions
- Pharmaceutical synthesis of chiral amines and alcohols
