An immobilised nitrogen-containing ligand is described comprising the reaction product of a compound of formula (I) wherein R 5 , R 6 , R 7 and R 8 are independently hydrogen, a saturated or unsaturated C1-C10 alkyl group, an aryl group, a urethane group, a sulphonyl group or form an imine group, R 1 , R 2 , R 3 , and R 4 are independently hydrogen, a saturated or unsaturated C1-C10 alkyl group or an aryl group and at least one of R 1 , R 2 , R 3 and R 4 is functionalised with a functional group, and a solid support having a site capable of reacting with said functional group. The nitrogen-containing ligand is useful for preparing immobilised catalysts for performing e.g. asymmetric catalysis. |
