2. Furthermore, studies using Xantphos ligands ( ligands with bulky backbones ) in hydroformylation have indicated an increase in the rate of catalysis in metal complexes that contain diphosphine ligands with larger bite angles.
3. Bidentate phosphine with a natural bite angle of 120?preferentially occupy diequatorial sites in a trigonal bipyramidal complex whereas a bidentate phosphine with a natural bite angle of 90?preferentially occupy apical-equatorial positions.
4. Bidentate phosphine with a natural bite angle of 120?preferentially occupy diequatorial sites in a trigonal bipyramidal complex whereas a bidentate phosphine with a natural bite angle of 90?preferentially occupy apical-equatorial positions.
