Bromoenynamides represent precursors to a diversity of azacycles by a cascade sequence of carbopalladation followed by cross‐coupling/electrocyclization, or reduction processes. Full details of our investigations into intramolecular ynamidecarbopalladation are disclosed, which include the first examples of carbopalladation/cross‐coupling reactions using potassium organotrifluoroborate salts; and an
