  • Water-insoluble ruthenium catalyst composition for use in aqueous hydrogenation reactions
    Patent number: 9758457
    Abstract: The invention relates to a method for converting a precatalyst complex to an active catalyst complex, wherein the precatalyst complex and the active catalyst complex comprise a ruthenium atom and an optically active ligand that is insoluble in water, and the active catalyst complex furthermore comprises a monohydride and a water molecule. The method comprises the steps of providing water as an activation solvent system with a pH value equal or below 2, and solving said precatalyst complex, an acid, and hydrogen therein. The invention further relates to a method for manufacturing a catalyst composition, a method for hydrogenating a substrate molecule and a reaction mixture.
    Type: Grant
