Sixteen substituted curcumin analogs are synthesized in one pot by iodine impregnated nano neutral alumina
catalyst under microwave irradiation. This catalyst shows higher reactivity by which it offered the reaction with higher
yields and less reaction time. The prepared catalyst was characterized by FE-SEM, EDX and BET isotherm surface area.
Also, the synthesized products were characterized by FT-IR, 1H NMR, 13C NMR, mass and elemental analysis.
