Abstract
An intramolecular direct arylation 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 direct arylation compared with the conventional methods. The ultrasonic irritation not only greatly promoted the conversion and selectivity of the direct arylation, but ...
