Palladium-catalyzed intermolecular aminocarbonylation/intramolecular amidation cascade sequences can be used to convert a range of 2-(2-haloalkenyl)aryl halide substrates efficiently and selectively to the corresponding 2-quinolones. Delaying the introduction of the CO atmosphere allows an amination/carbonylation sequence and the preparation of an isoquinolone.
