Twinphos: A New Family of Chiral Ferrocene 7Wra-Phosphine Ligands for Asymmetric Catalytic Transformations

摘要

A new family of chiral ligands for asymmetric homogeneous hydrogenation has been developed. The performance of mono- and bis-rhodium complexes of these chiral ferrocene tetraphosphine ligands in the hydrogenation of model substrates was surveyed in comparison to their ferrocene bis-phosphine analogs.
