Investigations concerning the optical induction in asymmetrichydrogenation reactions confirm the stereochemical control function of mono- and di-substituents in seven-membered chelateringdiphosphines, whereby the bulkiness of substituents in the backbone of the ligands is reflected in higher enantioselectivities.
