Abstract

Abstract The reactions of silyl enol ethers with carbonyl compounds are activated by heterogeneous catalysis. Caesium fluoride is the best catalyst. Unsaturated ketones are directly obtained by condensation reactions of sily enol ethers with aldehydes and ketones. 1, 4 Addition with α, β unsaturated carbonyl compounds gives 1, 5 dicarbonyl products. This method is very convenient and the compounds obtained can easily be separated. We ...
