    • Abstract

       

      Solid supported copper (0) nanoparticles were prepared by physical adsorption of copper (0)nanoparticles (synthesized through bottom-up approach) on the solid supports such as silica, HAP, cellulose andbasic alumina. Studies comparing these supported catalysts were done with the synthesis of arylmethylene-bis-(3-hydroxy-2-cyclohexene-1-one) via the cascade Knoevenagel/Michael reaction. The highly efficient catalystwas characterized by spectroscopic techniques like XPS, TGA, EDX, SEM, TEM and AAS. The biologicalimportance of arylmethylene-bis-(3-hydroxy-2-cyclohexene-1-one) enforced us to synthesize these compoundscatalytically using solid supported copper (0) nanopartcles.
