Abstract
This invention relates to a process for the preparation of aluminum alloys having a high reducing capacity for use in reductions in organic chemistry. According to this method a discontinuous heterodisperse superficial alloy is formed by subjecting an aluminum alloy prepared by a metallurgical process to superficial activation and/or treating aluminum with a salt of a metal having a greater normal electrode potential than that of aluminum; whereby the solution of said metal in a protic solvent is reacted with granular aluminum and/or an aluminum alloy. The catalyst prepared according to the invention is especially suitable for the reduction of a nitro or nitroso group into an amino group. The aluminum alloys having a high reducing capacity are also within the scope of the invention.
