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.
