摘要
Rare ruthenium(II) complexes bearing a pyridyl-based pyrazolyl-imidazolyl ligand were synthesized and exhibited exceptionally high catalytic activity in the transfer hydrogenation of ketones in 2-propanol at 82 degrees C or room temperature, reaching 100% conversion of the substrates and final TOFs up to 7.2 x 10(5) h(-1) with 0.05 mol % catalyst at 82 degrees C and 55 800 h(-1) with 0.1 mol % catalyst at room temperature.
