摘　　要：K5CoW12O40 was used as a highly effective catalyst for the benzylation of 1,3-dicarbonyl compounds, β-Keto enol ethers were obtained when cyclic 1,3-dicarbonyl compounds used in this conditions instead of linear ones. The present methodology offers a practical, simple, mild, environmentally friendly, and time-saving method for etherification. Very low loading of catalyst, ease of workup, ease of handling, and reusability of catalyst are other advantages of this catalyst.K5CoW12O40 was used as a highly effective catalyst for the benzylation of 1,3-dicarbonyl compounds, β-Keto enol ethers were obtained when cyclic 1,3-dicarbonyl compounds used in this conditions instead of linear ones.
