VIP: 1H DOSY Spectra of Highly Enantioselective Ligands: A Fast and Simple NMR-Specroscopy Method to Optimize Catalytic Reaction Conditions

Katrin Schober, Evelyn Hartmann, Hongxia Zhang, and Ruth M. Gschwind*

The first aggregation study of selected phosphoramidite ligands and their transition metal complexes is presented. The aggregation trends reveal that for highly selctive ligands, an easy and fast DOSY screening of the free ligands allows a prediction of the aggregation trends of their transition metal complexes even without knowledge about the complex structures. Furthermore, the limits of applicability of this method are discussed and the type of interligand interactions is addressed.
