We report an asymmetric homocoupling of ortho-(iodo)arylphosphine oxides and ortho-(iodo)arylphosphonates resulting in highly enantioenriched axially chiral bisphosphine oxides and bisphosphonates. These products are readily converted to enantioenriched b

Three new biaryl phosphine ligands 4a-c have been prepared and their application in the Ru-catalyzed asymmetric hydrogenation of β-ketoesters investigated. Ruthenium catalysts containing these ligands are highly effective in the hydrogenation of β-ketoesters with up to 99.9% ee being obtained.
