摘要：An oxidant-free dehydrogenation of alcohols in the aqueous phase was developed for the first time using water-soluble poly(N-vinyl-2-pyrrolidone) (PVP)-stabilized ruthenium nanoparticles with an ionic liquid as a promoter. The present catalytic system was highly efficient and stable for the catalytic dehydrogenation of various alcohols. It was found that the basic ionic liquid 1-n-butyl-2,3-dimethylimidazolium acetate ([BMMIM]?OAc) additive played a crucial role in enhancing the catalytic activity and stability of ruthenium(0) nanoparticles. A reaction kinetics study and 1H NMR analysis demonstrated that the basic ionic liquid and ruthenium nanoparticles exerted a synergetic effect for the dehydrogenation reaction.
