Zusammenfassung:	The present invention relates to a method for processing of hydrogen for the reductive acylation of nitro, azido and cyano arenes. More particularly, this invention relates to an improved process for the preparation of amides and anilides using C>37< carboxylic acids as proton source/acylating agents employing Fe?3+>-montmorillonite as a catalyst. L'invention concerne un procédé de traitement d'hydrogène utilisé dans l'acylation réductive de nitro, azido et cyano arènes. Plus particulièrement, cette invention concerne un procédé amélioré de préparation d'amides et d'anilides au moyen d'acides carboxyliques en C3-C7 en tant qu'agents d'acylation/source de protons utilisant du Fe-montmorillonite en tant que catalyseur.
