excellent yields by the palladium-catalyzed cyclocarbonylation-decarboxylation of diethyl(2-iodoaryl)malonates with vinyl ketones and carbonmonoxide. The reaction may proceed via the formation of a keto-diester, followed by oxidative addition, CO insertion, intramolecularcyclization, and decarboxylation to give the enolic substituted 2-acyldihydronaphthalenones.
