Abstract
AbstractImproved palladium‐catalyzed carbonylative Heck coupling reactions of aryl bromides with styrenes are described. Applying a [{(cinnamyl)PdCl}2]/PPh3 catalyst system, >20 chalcones with various functional groups were synthesized in 45–90 % yield. The reaction mechanism of this coupling reaction was studied by detailed DFT computations, which show that the carbonylation step is reversible.
