Outline of Final Research Achievements

This study has investigated the development of highly effective and selective catalysts based on transition metal complexes containing polydentate ligands. In particular, this study has developed new pincer complexes that contained both electron donating N-heterocyclic carbene and chiral oxazoline fragments. This ligand produced transition metal complexes containing Rh and Ru, which displayed high activity in reduction of both aromatic rings and carbonyl groups. In addition, Rh complexes was found to serve as a highly enantioselective catalyst in asymmetric alkynylation reaction of ketones. The Ru complex also showed a catalytic activity in three-component coupling reaction. Fe silyl and stannyl complexes were prepared by oxidative addition of C-Si and C-Sn bonds. The iron silyl complex was found to be active in hydrosilylation of ketones.
