Abstract
A three-component coupling of tetramethylammonium pentacarbonyl (acyl) chromates, aryl iodides, and CO takes place under CO atmosphere in the presence of a catalytic amount of Pd (PPh 3) 4 to afford the corresponding unsymmetrical α-diketones in good yield. By performing the reaction under argon atmosphere, unsymmetrical ketones are prepared instead of α-diketones.
