A Heck of a reaction: With a PCy3‐supported Pd catalyst, arylcarboxylicacids cross‐couple to saturated propiophenonesthrough a combination of decarboxylation and dehydrogenation to give chalcones bearing a variety of functional groups in generally good yields (see scheme). Furthermore, a one‐pot procedure, involving this reaction and a subsequent selective hydrogenative cyclization process, has
