A ligand of formula (I) is described
wherein R 1 , R 3 , R 5 , R 6 , R 7 and R 8 are hydrogen, characterized in that R 2 and R 4 are functional group-containing aryl groups in which the functional groups are selected from the group consisting of halogen (Cl, Br, F or I), hydroxyl, alkoxy, carbonyl, carboxyl, anhydride, carbene, methacryl, epoxide, vinyl, nitrile, mercapto, amine, imine, amide and imide. The ligand is useful for preparing immobilised catalysts for performing e.g. asymmetric catalysis. |
