Biaryl motifs are essential structural features in several drugs and functional molecules. Cyclic diaryliodonium has been scarcely explored as a bifunctional agent compared to ring opening and annulation reactions. Herein, a three-component cascade approach is developed to synthesize bifunctionalized biaryls employing cyclic diaryliodoniums as a biarylating agent. The mild conditions enabled a vast array of biarylated products in good yields in a single step. Furthermore, preliminary mechanistic details and photophysical properties have been investigated.
