Abstract:
The work being presented in this paper demonstrates the simple and efficient "transition-metal-free" and "light-mediated" synthetic protocol for the synthesis of aryl iodides/biaryls/alkynes from aryl bromides. Under ultraviolet irradiation and in basic aqueous media, aryl bromides undergo transformation into aryl iodides which efficiently couple via a cascade reaction with a wide range of terminal alkynes/unactivated arenes to generate target molecules under green conditions.
