Palladium-Catalyzed Alkenylation of Ketone Enolatesunder Mild Conditions.

A protocolfor a mild, catalytic, intermolecular alkenylation ofketone enolates has been developed using a Pd/Q-Phos catalyst. Efficientintermolecular coupling of a variety of ketones with alkenyl bromideswas achieved with a slight excess of LiHMDS and temperatures downto 0 °C. [ABSTRACT FROM AUTHOR]
