Outline of Final Research Achievements

We synthesized reactive late-transition-metal (Ru, Rh, and Ir) complexes supported by silyl chelate ligands involving a weakly coordinating oxygen ligand moiety (bis(silyl) and silyl(phosphine) xanthene derivatives) and also investigated reactivity and catalytic functions of these complexes. As a result, the following unique reactions catalyzed by some of these complexes were developed: (1) silylation reactions of arylalkynes via activation of an arene C-H bond under mild conditions, (2) alkene hydrogenation through reversible hydrogenation/dehydrogenation on a metal-silicon bond.
