Abstract

The addition of water and methanol to the carbonyl substituents in the dicationic bis(arene)ruthenium complexes [(p-cymene)Ru(C6H5CHO)][OTf]2 (1) and [(p-cymene)Ru(C6H5C(O)CH3)][OTf]2 (2) is remarkably favorable-the equilibrium constants for these reactions are 1 million times greater than those for uncomplexed benzaldehyde and acetophenone. The addition of methanol to the carbonyl group in the o-anisaldehyde complex, [(p-cymene)Ru(C6H4{OCH3}CHO)][OTf]2 (6), occurs with a high degree of kinetic selectivity (94% de).
