Definitions
- the present invention relates to 1-position with a C-bonded radical and in the 2,3-position with a P- or S-linked radical substituted ferrocenes, their preparation, metal complexes of transition metals (for example TM ⁇ metals) with these ligands, and the use of the metal complexes in the homogeneous, stereoselective synthesis of organic compounds.
- transition metals for example TM ⁇ metals
- Chiral ligands have proven to be exceptionally important tools for catalysts in homogeneous stereoselective catalysis.
- the effectiveness of such catalysts often turns out to be specific for certain substrates.
- chiral ligands which are easy to prepare and which give good results in stereoselective catalytic reactions.
- ligands whose properties can be adapted and optimized for specific catalytic problems. For this ligands are particularly suitable, which can be modular.
- Ferrocene is a very useful backbone for the preparation of ligands that has been successfully used to provide different substitutions with secondary phosphine residues.
- Kagan et al. [(Argouarch Arg, O. Samuel, O. Riant, J.-C. Daran, H. Kagan, Eur. J. Org. Chem. (2000) 2893-2899] have recently discovered new ferrocene-1,2-diphosphines described as ligands with the following basic structure, but which have only one planar chirality:
- metallation with, for example, lithiumbutyl
- metallation of ferrocenes having a chiral substituent, such as 1- (dimethylamino) -eth-1-yl
- the metal can then be replaced in a conventional manner with halogen such as bromine.
- halogen such as bromine.
- the hydrogen atom in the ortho position to the bromine atom can be easily and very selectively metallated with lithium bases and then reacted with secondary phosphine halides.
- monophosphines can then be unexpectedly converted to ferrocene-1,2-diphosphines by replacement of the bromine atom, although this position is sterically strongly shielded.
- these ligands possess significantly better stereoselectivities, especially in hydrogenations.
- These ligands are also very modular and can be optimized for a given catalytic problem by varying the chiral substituent and the phosphines. The catalyst activities and conversions depend on the substrate used and are good to very high (up to 100%).
