Abstract
The
vastly increasing application of chiral Cp ligands in asymmetric
catalysis results in growing demand for novel chiral Cp ligands. Herein,
we report a new class of chiral Cp ligands based on 1,1′-spirobiindane,
a privileged scaffold for chiral ligands and catalysts. The
corresponding Rh complexes are shown to be excellent catalysts in
asymmetric oxidative coupling reactions, providing axially chiral
biaryls in 19–97% yields with up to 98:2 er.
