Intercalation of metal complexes into smectites is one of the useful methods for the preparation of supported metal complex catalysts. Smectites can intercalate metal complexes as well as various organic compounds simultaneously. Multiple modification of clays with these guest compounds (tuning guests) can be applied to the preparation of catalysts for molecular recognition reactions such as shape selective hydrogenation and asymmetric hydrogenation. <BR>In this article, clay-supported metal complexes were prepared by various methods such as cation exchange and ligand exchange methods. For the ligand exchange method, clays were modified with tuning guests including alkylammonium ions and alkylsilanes. These clay-supported catalysts were used for catalytic hydrogenations of alkenes, alkynes, aldehydes, and ketones and their shape selectivities were studied
