Thianthrenium salts have emerged as one of the most versatile reagents, gaining significant popularity within synthetic community for their utility in construction C-C and C-X (X = N, O, S, P, halogens) bonds. The use photoredox transition metal catalysis with thianthrenium C-heteroatom bond formation is well established. However, these methods require elevated temperatures, expensive catalysts, ligands under stringent conditions effective execution. In contrast, photocatalysis- transition-metal-free approaches constructing bonds using salt derivatives become increasingly sought after. this regard, electron-donor-acceptor (EDA)-complex reactions a powerful strategy organic synthesis, eliminating need photocatalysts visible light irradiation. EDA-complex photochemistry exploits electron-acceptor properties salts, facilitating rapid generation radical intermediates via C-S cleavage. These play pivotal role enabling variety valuable formations. Perspective, we highlight advances EDA-complex-mediated involving mechanisms, substrate scope, limitations For sake brevity, article organized into five main sections: (1) Nitrogen-based donor reactions, (2) Oxygen-based (3) Sulfur-based (4) Phosphorus-based (5) π-based focus on C-C, C-S, C-B C-P
