Chalcones made easy: Carbonylative Heck reactions of aryl and alkenyl triflate derivatives with carbon monoxide and aromatic olefins proceed in the presence of palladium catalysts (see scheme; dppp=1,3-bis(diphenylphosphino)propane, Tf=triflate; R=aryl, vinyl). With this process, the gap between the Suzuki and Sonogashira carbonylative reactions is finally bridged.
