Asymmetric hydrogenation in water by a rhodium complex of sulfonated 2,2′bis(diphenylphosphino)-1,1′-binaphthyl (binap)
Abstract
The synthesis of sulfonated 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (binap) is reported; a rhodium complex of this ligand is the first to perform asymmetric hydrogenation in neat water with optical yields as high as those obtained in nonaqueous solvent.
