16-Electron iridium complexes bearing a silyl-1,8-naphthyridine-based bidentate ligand (napySi), Ir(κ2Si,N-napySi)(H)(coe)X [X = Cl (1) and Me (2)], were synthesized and characterized. Single-crystal X-ray diffraction studies revealed that both1and2have a square-pyramidal geometry with the silyl moiety occupying the apical position and the nitrogen lone pair of napySi adjacent to the vacant metal center. Methyl complex2catalyzed hydrogenation of alkenes with H2(1 atm) at room temperature. This hydrogenation proceeded significantly faster than that catalyzed by a related complex with no nitrogen lone pair adjacent to the metal. Based on this result, we suggest a possible catalytic cycle including cooperative activation of H2between the nitrogen lone pair and the metal center for this system.
