Abstract

SO3H-Functionalized ionic liquids were found to be efficient and reusable catalysts in the hydroamination of sulfonamides, carboxamides, p-nitroaniline and carbamates with nonactivated alkenes. The hydroamination could be performed on a large scale and the acidic ionic liquid catalyst could be reused successfully.
