Abstract

The monodentate ligand combination approach is a new concept in asymmetric catalysis, in which a catalyst, based on a combination of two different monodentate ligands (hetero-complex), leads to improved results compared to catalysts based on only one of the two ligands (homo-complexes) (Scheme 1). 1 The hetero-complexes are formed in situ by mixing the metal precursor with the ligands. This means that the overall activity and selectivity of ...
