During these last twenty years, the syntheses of water-soluble cyclodextrins modified by
phosphino groups or imidazolium groups (as precursors of N-heterocyclic carbenes) have been reported.
These ligands based on cyclodextrins allowed performing transition metal catalyzed reactions
in water. In this review, the molecular recognition properties, the ability of these ligands to immobilize
transition metal complexes in water as well as their implications in aqueous organometallic catalysis
Keywords: Aqueous organometallic catalysis, carbene, cyclodextrin, inclusion complex, ligand, mass transfer agent, phosphane.
