摘要：

Three pairs of new axially dissymmetric diphosphine ligands, (R)-(-)- and (S)-(+)-2,2'-bis(dicyclohexylphosphino)-1,1'-binaphthyl [(R)-(-)- and (S)-(+)-Cy-BINAP], (R)-(+)- and (S)-(-)-2,2'-bis(diphenylphosphino)-5,5',-6,6',7,7',8,8'-octahydro-1,1'-binaphthyl [(R)-(+)- and (S)-(-)-H8-BINAP], and (R)-(-)- and (S)-(+)-2,2'-bis(dicyclohexylphosphino)-5,5',6,6',7,7',8,8'-octahydro-1,1'-binaphthyl [(R)-(-)- and (S)-(+)-Cy-H8-BINAP], have been synthesized and their absolute configurations have been determined on the basis of an X-ray analysis and CD spectra.
