benzylation of 1,3-dicarbonylcompounds. β-Keto enol ethers were obtained when cyclic1,3-dicarbonylcompounds 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
