A catalyst generated from Pd(OAc)2 and dppp is effective for the direct intramolecular arylation of alkenyl triflates. Conjugated alkene-arene-containing carbocycles are produced in good yield. The process tolerates a variety of aryl substituents as well a simple heteroaryl groups. Electron-deficient aryl rings deliver faster reactions.
