text: Most chiral phosphines are C-symmetric diphosphines.  Famous examples are DIPAMP and BINAP.  These chelating ligands support catalysts used in asymmetric hydrogenation and related reactions.  DIPAMP is prepared by coupling the P-chiral methylphenylanisylphosphine.
  P-Chiral phosphines are of particular interest in asymmetric catalysis. P-Chiral phosphines have been investigated for two main applications, as ligands for asymmetric homogeneous catalysts and as nucleophiles in organocatalysis.
