| titleOfInvention | METHOD FOR PRODUCING SOLUBLE CYCLOALKYL PHOSPHINOXIDES |
| abstract | The invention relates to a process for preparing gesaettigten Cycloalkylphosphinoxiden by catalytic hydrogenation of analogous Arylphosphinoxiden in the presence of a straegerfreien Pt / Rh bimetallic catalyst with mild reaction compounds (30 to 40C) and low hydrogen pressures (1 to 3 MPa) in an organic solvent mixture (ethanol / glacial acetic acid ). The process which leads to high yields has the advantage of preserving the optical activity of optically active starting materials and allows the preparation of basic phosphines which can be used in versatile ways as ligands for homogeneous hydrogenations and for asymmetric syntheses {cycloalkylphosphine oxide; catalytic hydrogenation; aryl phosphine oxide; basic phosphine; Ligand for homogeneous hydrogenation; asymmetric synthesis; carrier-free Pt / Rh bimetallic catalyst} |
