  • Enzymatic reductions with dihydrogen via metal catalyzed cofactor regeneration
    Patent number: 6599723
    Abstract: The invention provides a process for reducing an unsaturated organic compound, comprising mixing the unsaturated organic compound and H2 in the presence of a catalyst to form a reduced organic product, wherein the catalyst comprises: a) at least one metal salt or complex, b) at least one nicotinamide cofactor; and c) a nicotinamide cofactor dependent enzyme, wherein: i) when the metal salt or complex is a platinum carbonyl cluster complex, the catalyst does not comprise a redox active dye; and ii) when the metal salt or complex is a rhodium phosphine complex, the nicotinamide cofactor dependent enzyme is not a mixture of horse liver alcohol dehydrogenase and lactate dehydrogenase.
