Abstract

A series of novel optically active diphosphine ligands, (4,4'-bi-1,3-benzodioxole)-5,5'-diyl-bis(diarylphosphine)s (6), which are called SEGPHOS, hasbeen designed and synthesized with dihedral angles in the Ru complexes being less than that in the corresponding BINAP-Ru complex. The stereorecognition abilities of SEGPHOS-Ru complex catalysts in the asymmetric catalytic hydrogenation of a wide variety of carbonyl compounds are superior to those observed with BINAP=Ru complex catalysts.
