(57) [Summary]nFerrocene-immobilized chiral ligands and metal complexes based on such chiral ligands useful for asymmetric catalysis are disclosed. The metal complexes of the present invention may be subjected to asymmetric reactions such as hydrogenation, hydride transfer, allylic alkylation, hydrosilylation, hydroboration, hydrovinylation, hydroformylation, olefin metathesis, hydrocarboxylation, isomerization, cyclopropanation, It is useful as a catalyst in Diels-Alder reaction, Heck reaction, isomerization, aldol reaction, Michael addition; epoxidation, kinetic optical resolution and [m + n] cycloaddition. The new ligand is effective for asymmetric Pd-catalyzed allylic alkylation and Ag-catalyzed [3 + 2] cyclization of azomethine ylide. |
