catalyzed hydroformylation reaction. The binding of chiral effectors in non-chiral [Rh(DIMPhos)] catalysts does not lead to enantioselectivehydroformylation, but the binding of either achiral or chiral effectors can significantly enhance the enantioselectivity induced by the chiral Rh-metal complexes. For example, the supramolecular complex [Rh]/[1S⊂L3] displays high regio- and enantioselectivity in the

The invention relates to a coordination complex system for chemically converting a substrate comprising a non-protein ligand having a first building block with at least one functional group and at least one donor moiety, which donor moiety is complexed to a metal selected from a transition metal and lanthanide or an organometallic precursor thereof, characterized in that the ligand further comprises at least one second building block not having a donor moiety and having at least one functional group that is complementary to the at least one functional group of the first building block, wherein the first building block and the second building block are non-covalently bonded through their functional groups. These coordination complex systems are used as a catalyst for chemical reactions such as hydroformylation, hydrogenation, transfer hydrogenation, hydrocyanation, polymerization, isomerization, carbonylation, cross-coupling, metathesis, CH-activation, allylic substitution, aldol condensation, and Michael addition, preferably to obtain chiral compounds.
