The higher the π‐acidity of the aldehyde ligand the more pronounced the chiral recognition in its bonding to the chiral complex 1. This emerges from low‐temperature NMR spectroscopic investigations on reactions of the complex 1 with the aromatic aldehydes 2, which, in addition, showed that the diastereomeric π‐aldehyde complexes of 1 and 2 interconvert intramolecularly via a σ‐aldehyde complex.
