An efficient and green protocol for the synthesis of pyrazoles derivatives by one–pot reaction of different 1,3–dicarbonyl compounds with hydrazines\hydrazides has been developed using nano–sulfated zirconia, nano–structured ZnO, nano–g–alumina and nano–ZSM–5 zeolites, as the catalyst. The optical properties of the nano–structured catalysts and organic molecules were studied. The advantages of methods are short reaction times and milder conditions, easy work–up and purification of products by non–chromatographic methods. The catalysts can be recovered for subsequent reactions and reused without any appreciable loss of efficiency.
