An efficient ligand- and transition metal-free procedure for the direct Csp2O bond formation for the arylation of 2-aryl-4-quinolones was developed. The synthesis of the starting quinolones was carried out under our optimized Cu-catalyzed CN bond formation conditions between 2′-bromoacetophenone and benzamide derivatives followed by cyclization. Easily prepared diaryliodonium salts were used as aryl
