Chapter 10: Host-guest chemistry in aqueous organometallic catalysis

Host-guest complexation relies on interactions of molecules through secondary chemical bonds. Such complexation can lead to formation of loose associations, as well as to that of very stable adducts. In formation of these addition compounds, important roles are played by hydrogen-bonding and hydrophobic interactions. In certain cases one of the reacting partners will wind up in a relatively enclosed space, embraced by the other reactant this is when the host-guest description is most appropriate. In general, any such interaction between host and guest is expected to change the properties of both molecules but it is the host molecule which...
