ABSTRACT:
A method of synthesizing a heteroleptic, multiple metal-containing metallocyclic catalyst, particularly suited for asymmetric catalysis, comprising combining a plurality of plural functional group-containing, monodentate ligands of complementary chirality, said plural functional groups being tethered to each other by tethers in the presence of a scaffold-structural metal Ms or derivative thereof, wherein at least one functional group on each ligand combines to ligate Msto form a bidentate, Mscentered ligand scaffold containing the remaining functional groups and combining said bidentate ligand scaffold with a catalytic metal Mcor derivative thereof whereby the remaining functional groups combine to ligate Mc, thereby forming said catalyst.
