Catalysts based on pillared clays were synthesized, by preadsorption of amines between the clay layers prior to pillaring with aluminium precursora, from Moroccan Ghassoulite clay. A comparison of catalytic activity, in the synthesis of benzothiazole and benzimidazole derivatives, of these catalysts is discussed. It is shown that Al-pillared (x CEC) catalyst can be quantitatively recovered and be reused effectively for many times.
