Phosphines and phosphites bite angle effects

Diphosphine ligands offer more control over regio- and stereoselectivity in many catalytic reactions the stability of the bidentate co-ordination reduces the

With the aim of rationalizing the effect of (wide) bite angle diphosphines in catalytic reactions a distinction can be made between two different effects, both related to the bite angle of diphosphine ligands [42]
