چکیده مقاله :
Transesterification, one of the most effective methods for ester synthesis, is usually conducted under acid or basicconditions. Although quite a few methods have been reported for transesterification, they are not general as far asp-ketoesters are concerned. Some of these methods used toxic, expensive reagents and in relatives large amount. Inthis research, transesterification reaction six types P-ketoesters achieved in present of Cu powder and Cunanoparticles as catalyst and P-ketoesters prepared using this method. Copper Nanoparticles is an efficient catalystfor the transesterification of p-ketoesters with several kinds of alcohols, leading to good yields with highselectivity.
