An intramoleculardirectarylation of various aryl bromides was performed using ultrasonic irradiation and a continuous flow capillary microreactor. The present procedure provided a higher functional group tolerance, ligand-free, milder reaction conditions and a shorter reaction time for the directarylation compared with the conventional methods. The ultrasonic irritation not only greatly promoted
