Abstract
A process for the preparation of amino halogeno aromatic compounds, according to which a halogenonitro-aromatic compound is brought into the presence of a nickel-, cobalt- or iron-based catalyst, preferably nickel-based, and, more preferably, Raney nickel, in the presence of an effective amount of iodide, at a temperature and hydrogen pressure sufficient to form said halogenoamino-aromatic compound.
