Stereospecific Deoxygenation of Phosphine Oxides with Retention of ConfiguraUsing Triphenylphosphine or Triethyl Phosphite as an Oxygen Acceptor. —
12- 179 tion
A novel HSiCl3-mediated oxygen transfer reaction between the phosphorus atoms allows a convenient synthesis of some electron-deficient chiral phosphine ligands such
as BINAP derivatives for the first time. Triphenylphosphine and triethyl phosphite
serve equally well as oxygen acceptors: the latter are advantageous due to the easier
work-up. The reaction of (XI) is carried out with retention of configuration. — (WU,
