The through-space CH/π attraction between the η<sup>6</sup> -arene ligand on Ru and the carbonyl aryl substituent (see transition states in picture) plays a key role in the enantioselective transfer hydrogenation of aromatic carbonyl compounds with 2-propanol or formic acid, catalyzed by chiral η<sup>6</sup> -arene-Ru<sup>II</sup> complexes.
