Abstract
Organic ligands that contain at least one aryl group are immobilized on a solid support. The organic ligands are of the type used to form a catalyst complex suitable for carrying out a catalytic reaction, preferably an asymmetric reaction. To immobilize the organic ligands, a tethering group is bonded to the ligand using, for example, a Friedel-Crafts acylation or alkylation reaction. The immobilization of the organic ligand can be carried out using a single reaction with the organic ligand.
