, p. 9899 - 9902 (2000)
Tris(trimethylsilyl)silane reacts with phosphine sulfides and phosphine selenides under free radical conditions to give the corresponding phosphines in good yields. Stereochemical studies on P-chiral phosphine sulfides show these reductions proceed with retention of configuration. (C) 2000 Elsevier Science Ltd.

Page/Page column 25, (2010/04/03)
The present invention relates to a method for increasing the enantiomeric excess of a chiral phosphine oxide, a chiral phosphine sulphide, a chiral phosphine-borane and a chiral phosphine imide said method comprising the steps of: (a) contacting said chiral phosphine oxide, sulphide, imide or borane with a solvent to form a slurry; (b) partitioning the phosphine oxide, sulphide, imide or borane either into the solvent or as an insoluble product; and (c) optionally, isolating the partitioned phosphine oxide, sulphide, imide or borane.
Chemo-, regio- and stereoselective conversion of P-chirogenic phosphorus borane complexes into their P=O or P=S derivatives

Chiral and achiral organophosphorus borane complexes are readily transformed into their corresponding phosphoryl or thiophosphoryl compounds in high yields using one-pot procedures with stereoselectivities reaching 100% in many cases. Both oxidation and sulfuration were performed under neutral or mild conditions and were applied to various organophosphorus borane complexes (phosphines, phosphinates, chlorophosphines, aminophosphines, etc.). In the case of the dissymmetric diphosphine or aminophosphine phosphinite ligands, the reaction of their diborane complexes proceeds regiospecifically to a single phosphorus group, affording the corresponding hybrid derivatives.
