This study introduces a visible light-mediated synthesis of 2,3-chalcogenil-dihydrobenzofuran through the oxyselenocyclization 2-allylphenols in presence chalcogenides. Emphasizing sustainability, this method is notably enhanced by proceeding under mild conditions, facilitated straightforward I2/SnCl2 as promoter and blue LED irradiation to activate process. A variety functional groups were effectively tolerated our developed approach, leading desired products with yields ranging from good excellent, demonstrating way versatility method. In addition, synthesized compounds characterized using 1H 13C NMR techniques.
