note = "Funding Information: In summary, highly convenient routes for the synthesis of enantiomerically pure P-chiral bi-and tridentate phosphine ligands have been developed. Whilst we have here focussed on the one set of ligands - tert-butyl and phenyl - with respect to the phosphine oxide, we are now preparing secondary phosphine oxides bearing different aryl and alkyl groups in our laboratory. The uses of all types for the preparation of phosphines and the application of both the phosphine oxides and the derived phosphines for asymmetric catalysis will be reported elsewhere.
