Abstract

Abstract Highly efficient Oppenauer-type oxidation of secondary alcohols to the corresponding ketones has been realized by means of the ruthenium (II) complex catalysts bearing a 2-(benzoimidazol-2-yl)-6-(3, 5-dimethylpyrazol-1-yl) pyridine ligand. The oxidation reaction underwent in the presence of acetone as oxidant under mild conditions, reaching final TOF values up to 3960 h− 1. The hemilability of the ligand is attributed to the high ...
