摘要 |
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. |

1. A method for obtaining a catalyst composition, comprising the steps of
a) providing water as a preparation solvent system, and b) adding to, particularly solving in, said preparation solvent system
a first catalyst composition comprising an optically inactive ligand and a ruthenium metal atom,an optically active ligand, wherein said optically active ligand is insoluble in water,a preparation surfactant that is capable of forming micelles in water and that is resistant to hydrolysis at pH≦2, andan acid,thereby yielding a second catalyst composition comprising said ruthenium atom and said optically active ligand, characterized in that the pH value of said preparation solvent system is equal or below 2 after addition of said acid. |
