Abstract

Introduction: TRANSESTERIFICATION, one of the most effective methods for ester synthesis is usually conducted under acid or basic conditions. Although quite a few methods have been reported for TRANSESTERIFICATION, they are not general as far as b-ketoesters are concerned.Aim: We have successfully performed TRANSESTERIFICATION of 6 type's b -ketoesters using Zinc powder and ZINC NANOPARTICLES as CATALYST. Comparison between the two CATALYSTs in both yield and time of reaction were also done.Materials and Methods: In this research, we study of reaction between benzoyl ethyl acetate with 3-phenyl -1- propanol, benzoyl ethyl acetate with cyclohexanol, ethyl benzoyl acetate with buthanol, ethyl benzoyl acetate with tertio buthyl alcohol, ethyl aceto acetate with 3-phenyl-1- propanol, ethyl aceto acetate reaction with n-penthanol.Results: Some of these methods use toxic and expensive reagents and in relatively large of amount. In this research, TRANSESTERIFICATION reaction six types b -ketoesters achieved in present of Zn powder and Zn nanoparticles as CATALYST and 5 b -ketoesters prepared using this method.Conclusion: ZINC NANOPARTICLES is an efficient CATALYST for the TRANSESTERIFICATION of b - ketoesters with several kinds of alcohols, leading to good yields with high selectivity.
