Two different reaction pathways, the enolate arylation and the acylation of the aryl halide, can be promoted by a Pd(0) catalyst starting from beta-(2-iodoanilino) carboxamides. The intramolecular acylation of beta-(2-iodoanilino) carboxamides reported here is the first example of a nucleophilic attack of a sigma-arylpalladium species at the carboxamide group, a framework that is usually inert toward organopalladium reagents.

The factors that control the chemoselectivity of palladium‐catalyzedcyclization reactions of (2‐iodoanilino)carbonyl compounds have been explored by an extensive experimental computational (DFT) study. It was found that the selectivity of the process, that is, the formation of fused six‐ versus five‐membered rings, can be controlled by the proper selection of the initial reactant, reaction conditions
