Chelating chiral diphosphines are often used as Ligands of organometallic c
omplexes. However monophosphines, or more generally ligands with one phosph
orus linked to one or several heteroatom, may also be useful. This review g
ives the main results obtained in that area, by considering the classes of
monodentate chiral ligands bearing one P(III) atom and involved in asymmetr
ic catalysis with organometallic complexes.
