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 1 H NMR analysis demonstrated that the basic ionic liquid and ruthenium nanoparticles exerted a synergetic effect for the dehydrogenation reaction.
