Patent ID: 7015342

Claim:
A ferrocenyl ligand of the general formula (II) wherein the S fc ,S enantiomer of the formula (IIIa) is present in excess in the stereoisomer mixture (IIa) or the R fc ,R enantiomer of the formula (IIb) is present in excess in the stereoisomer mixture (IIb) and R′ and R″ are radicals which can be independently selected from the group consisting of H, CH 3 and mixtures thereof or can be a linker which connects the ligands to a polymeric support and the radicals, R′″ are radicals which can be independently selected from the group consisting of H, (C 1 –C 4 )-alkyl and mixtures thereof and the radicals, R 5 can be, independently of one another, radicals selected from the group consisting of C 6 -aryl, C 5 –C 6 -cycloalkyl, adamantyl, C 1 –C 4 -alkyl and mixtures thereof, where the radicals R 5 may bear one or more (C 1 –C 4 )-alkyl substituents and R 2 is hydrogen or a (C 1 –C 4 )-alkyl radical and R 11 is a (C 1 –C 4 )-alkyl radical.
