Synthesis and applications of new catalytic materials based on nanoporous materials will be presented. The first Pauson-Khand catalysts using metallic cobalt supported on mesoporous silicas are developed. The catalyst exhibited excellent performance for various intramolecular Pauson-Khand reactions. In addition, the catalyst can be recycled and reused many times without losing its catalytic activity. New heterogeneous catalysts employing a proline-derived ligand immobilized on mesoporous silicas were developed. Asymmetric diethylzinc addition to benzaldehyde was carried out using the catalysts. High enantioselectivity (75% e.e.) was achieved when both TMS-capping and n-BuLi addition were applied for the large pore-sized SBA-15 based catalyst.
