Cu(II)-acetohydrazide functionalized CMK-3 and MCM-41 mesoporous materials prepared by a simple, efficient and less expensive protocol. These catalysts are carefully characterized by SEM, XRD, TGA, FT-IR, EDX, ICP‐OES and BET techniques. The obtained nanostructured compounds were also used as a green, efficient, heterogeneous and reusable catalytic systems for the synthesis of 2-amino-4-H-pyran and 2,4,5-trisubstituted imidazole derivatives. Also the results and behavior of the two catalysts were comparable in some cases. The synthesized nanocatalysts could be easily recovered from the reaction mixture and reused many times without significant loss of their catalytic activities.
