The reaction was catalyzed by copper, a cheap transition metal in a weakly basic medium (K3PO4) at room temperature. To carry out this study, we first had to synthesize the monoalkylated ¦Â-diketones 1. Afterwards, ¦Á,¦Â-unsaturated ketones 2 were obtained with high yields around 80%. Finally, all the products were characterized by 1H NMR, 13C NMR, and HRMS spectra. %K Monoalkylated < %K i> %K ¦Â< %K /i> %K -diketone %K < %K i> %K ¦Á< %K /i> %K < %K i> %K ¦Â< %K /i> %K -Unsaturated Ketones %K Copper-Catalyzed %K C-C(O)C Bond Cleavage %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=125563
