Used as a highly efficient arylating agent in organic synthesis, particularly in photoredox catalysis and radical reactions. It serves as a source of aryl radicals under mild conditions, enabling the formation of carbon–carbon and carbon–heteroatom bonds. Commonly applied in late-stage functionalization of complex molecules, including pharmaceuticals and agrochemicals, due to its stability and selectivity. Also utilized in materials science for the synthesis of conjugated organic systems and functionalized aromatic compounds. Its triflate counterion enhances solubility in polar organic solvents, facilitating homogeneous reaction conditions.
