A relationshipbetween the structure of biaryl atropisomeric diphosphine ligands and their efficiency in model rhodium catalyzed asymmetriccatalytichydrogenation reactions have been studied with an attempt to separate the two main factors influencing the performance of the ligand in the catalyst core namely, the steric and the electronic factors. A series of new biaryl atropisomeric bisphosphines
