ABSTRACT

The catalytic hydrogenation of nitroarenes, including a series of nitroferrocenyl derivatives, to aminoarenes has been successfully achieved in the ionic liquid [bmim][BF4]. The isolated yields of the aminoarenes are very good and recycling of the solvent and catalyst has been achieved.

Keywords: Aminoarenes, hydrogenation, ionic liquids, nitroarenes, ferrocenes
