respective ionic liquids. Among the several preapered ionic liquids, strong acidic imidazolium based butylsulfonic acid (6) showed the best activity with a maximum of 84% yield of condensation product. This strategy offers significantly highyield production of condensation products of furan and furfural as compared to the traditional mineral acid route. The activity and stability of the -SO3H functionalized
Six Brønsted acidic ionic liquids (BAILs) composed of [HSO4] were prepared, characterized, and used as catalysts of low dosage in the synthesis of isoamyl salicylate.

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
