Some recyclable SO3H-functionalized ionicliquids have been used as catalysts in water for the aza-Michael reactions of amines with α,β-unsaturated compounds to produce β-amino compounds. High yields of the products, short reaction times, mild reaction conditions, simple experimental procedure, reusable catalysts and no obvious loss of the catalytic activity make this protocol a contribution to organic

and Brφnsted acidfunctionalizedionicliquid was applied, for the first time, to the one-pot hydrogenation of nitrobenzene to p-aminophenol. Our results indicate that the PAP selectivity of Ir/C and [SO3H-bmim][HSO4] Brφnsted functionalizedionicliquid was far more than that of the traditional Pt/C and sulfuric acidcatalyst system. Furthermore, the dually functionalizedionicliquid ([HSO3-b-N-Bu3][HSO4])

SO3H-functionalized Brønsted acidic ionicliquids (BAILs) were synthesized and utilized as highly efficient catalysts for the production of fructone via the acetalization reaction of ethyl acetoacetate with ethylene glycol. In comparison with conventional H2SO4 and cation exchange resins, the BAILs N-(4-sulfonic acid) butyl triethylammonium hydrogensulfate ([BSEt3N][HSO4]) of strongacidities exhibited excellent
