Kt. Wan et Me. Davis, ASYMMETRIC HYDROGENATION IN WATER BY A RHODIUM COMPLEX OF SULFONATED 2,2'-BIS(DIPHENYLPHOSPHINO)-1,1'-BINAPHTHYL (BINAP), Journal of the Chemical Society, Chemical Communications, (16), 1993, pp. 1262-1264
The synthesis of sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthy
l (binap) is reported; a rhodium complex of this ligand is the first t
o perform asymmetric hydrogenation in neat water with optical yields a
s high as those obtained in nonaqueous solvent.
