摘要

A new chiral bisphosphine ligand ((R)-2-diphenylphosphino-2′-diphenylphosphinomethyl- 1, 1′-binaphthyl) was synthesized from enantiomerically pure (R)-1, 1′-binaphthalene-2, 2′-diol. Rhodium (I) complexes of this bisphosphine ligand have been used as catalysts for asymmetric hydrogenation of α-alkylstyrenes to give the corresponding aromatic hydrocarbons in up to 77% ee.
