Used as a highly efficient arylating agent in organic synthesis, particularly for transferring aryl groups under mild conditions. It is effective in metal-catalyzed and metal-free reactions, enabling the formation of carbon–carbon and carbon–heteroatom bonds. Commonly applied in the synthesis of complex molecules such as pharmaceuticals and functional materials due to its stability and reactivity. Also utilized in photo-induced reactions for surface modifications and polymer chemistry. Its triflate counterion enhances solubility in polar organic solvents, making it suitable for a wide range of reaction media.
