The virtue of enantiomers: A general method has been developed for measuring the individual contributions of noncovalent interactions within transition-metal complexes and dissecting them from electronic effects. On Pd complexes with one enantiopure and two enantiomeric phosphoramidite ligands, it was experimentally shown that modulations in extended CH–π and π–π interaction interfaces provide a ΔΔG value that is significant for stereoselection.
