Synthesis of 1,4-Diketones by Palladium-Catalyzed Reductive Coupling of Acid Chlorides with (E)-1,2-Bis(tri-n-butylstannyl)ethene or β-Stannyl Enones

Article abstract of DOI:10.1021/jo00045a002

The palladium-catalyzed coupling of acid chlorides with (E)-1,2-bis(tri-n-butylstannyl)ethene or β-stannyl enones gives butane-1,4-diones directly by reduction of the intermediate enedicarbonyl derivative by a palladium hydride derived from n-Bu3SnCl.
