Supported catalysts have become valuable tools for simplified product isolation and catalyst recycling. The common method is covalent attachment to a solid support. An alternative strategy is to immobilize catalysts by non-covalent bonding through hydrogen bridges, ionic, hydrophobic or fluorous interactions. Compared to covalent attachment, such non-covalent approaches increase the flexibility in the choice of the support-material, reaction conditions and work-up strategies. Numerous catalytic reactions employing one of these non-covalent fixation strategies have meanwhile appeared in the literature.
