Abstract:
    The present invention describes novel chiral rhodium-diphosphine complexes having the formula [Rh(X) (Y) (L-[0],1,2)] wherein X, Y and L have the meanings cited in the claim I. The invention also describes processes for manufacture of the above complexes. These complexes are used in asymmetric hydrogenations.
