A supported catalyst having rhodium particles with an average diameter of less than 1 nm disposed on a support material containing magnetic iron oxide (e.g. Fe.sub.3O.sub.4). A method of producing the supported catalyst and a process of reducing nitroarenes to corresponding aromatic amines employing the supported catalyst with a high product yield are also described. The supported catalyst may be recovered with ease using an external magnet and reused.

The invention discloses a method for the preparation of fluoro alkylated compounds by homogeneous Ni catalyzed fluoro alkylation with fluoro alkyl halides in the presence of a base.
