A novel cationic dinuclear ruthenium complex: Synthesis, characterization and catalytic activity in the transfer hydrogenation of ketones
摘要:
A novel cationic dinuclear ruthenium complex [RuCl(HL)(TFTPP)](2) (H2L = 2,6-bis(5-phenyl-1H-pyrazol-3-yl) pyridine; TFTFP = tri(p-trifluoromethylphenyl)phosphine) has been synthesized and characterized by (31)p{H-1} NMR, H-1 NMR, elemental analysis and X-ray crystallography. This complex is the first cationic dinuclear ruthenium complex bearing N-4 ligand characterized by single crystal X-ray analysis. It exhibits good catalytic activity for the transfer hydrogenation of ketones in refluxing 2-propanol. (C) 2011 Elsevier B.V. All rights reserved.
