Abstract
Clay- and zirconium phosphate-supported metal complexes were prepared by various methods such as cation exchange, chemical anchored ligand, and interlayer polymerized ligand methods. Multiple modification of smectites with metal complexes and various organic guests (tuning guests) can be applied to the preparation of catalysts for the molecular recognition reactions such as shape selective, chemoselective, regioselective, and asymmetric hydrogenations. Especially, chiral phosphine-Rh complexes intercalated in hectorite exhibited both of size and asymmetrical recognition simultaneously in the hydrogenation of itaconates.
