چکیده
|
In this study, zinc oxide (zno) nanoparticles have been synthesized as a new recyclable solid acid catalyst. techniques such as fe-sem, tem, and xrd were used to characterize as prepared nanocatalyst. then, the catalyst was used for one-pot three components synthesis of tandem knoevenagel- michael-cyclocondensation reaction from various aldehydes, dimedone, and malononitrile in ethanol under reflux conditions. the attractive features of this process are easy work-up, reusability of the catalyst, excellent yields, short reaction times, and mild reaction conditions.
