Abstract
Arene ruthenium(II) reduced Schiff base complexes of formulation [(η6-p-cymene)RuCl(Ln)] (1-5, n=1-5) were prepared by reacting [(η6-p-cymene)RuCl2]2 with HLn in the presence of sodium carbonate in CH2Cl2. The complexes contain an η6-p-cymene group, a chloride and a bidentate chelating N,O-donor ligand. The molecular structure of [(η6-p-cymene)RuCl(OC6H4-2-CH2NHC6H4-p-Me)] (1) has been determined by X-ray crystallography. The complexes are found to be catalytically active for transfer hydrogenation of acetophenone to (±)1-phenylethanol in the presence of KOH and isopropanol showing percent conversion of 98 with the catalysts having a bulky substituent adjacent to the O- and N-donor sites of the auxiliary ligand.
