Two Stereoinduction Events in One C-H Activation Step: A Route towards Terphenyl Ligands with Two Atropisomeric Axes.

This synthesis of original chiral scaffolds-ortho-orientated terphenyls presenting two atropisomeric Ar-Ar axes constitute a unique foundation for building up a library of enantiomerically pure bidentate ligands, such as the new ligands S/N-Biax and diphosphine BiaxPhos.
