【Abstract】 Conjugated double bonds of arene structure are difficult to activate compared to those of alkenes; therefore, the rate of arene hydrogantion is usually much slower. Ionic copolymer containing parts of poly( N-vinyl-2- pyrrolidone) and ionic liquid acts as a protecting agent and dissolves well in the imidazolium ionic liquid. The rhodium nanoclusters maintain stable under forcing conditions of 40 atm H2 and 75 ℃。The hydrogenation rate of arenes catalyzed by the rhodium nanoclusters are fast, resulting high conversions to the complete hydrogenation products. The rhodium are immobilized in the ionic liquid phase and the organic products can be obtained free of metal pollutant with easy separation of decantation from the ionic liquid.更多还原
