摘要：A new natural clay-based support, doped with a Lewis acid (Cu-bentonite), was used inheterogeneous catalysis for the efficient synthesis of benzimidazoles, benzoxazoles andbenzothiazoles. The salient features of the present method are the mild conditionsrequired, short reaction times, high yields, and recyclability of the catalyst. The methodhas the advantage of being very stable, non-corrosive, with a low toxicity and highselectivity.
