N-tosylhydrazones derived from a wide variety of aryl, alkyl and heteroaryl aldehydes undergo smooth coupling with 5,5-dimethylcyclohexane-1,3-dione under transition metal and base free conditions to generate tetraketo compounds in high yields. In presenc

Catalytic activity of CsxH3-xPW12O 40 catalysts were investigated in the synthesis of β-ketoenol ethers. It was found that activity; acidity, solubility and consequently, recoverability of these catalysts are related to cesium content. A series of β-ketoenol ether derivatives were synthesized by using Cs 2.5H0.5PW12O40 catalyst in high to excellent yields. This catalyst showed highest surface acidity and lowest solubility in reaction media in comparison with the other cesium content salts.
Different products in the reaction of the alcohols with cyclic and acyclic 1,3-dicarbonyl compounds: K5CoW12O40 as an electron transfer nano 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. 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.
