Used as a highly active catalyst in cross-coupling reactions, particularly in carbon–carbon and carbon–heteroatom bond formations. Its gold-based structure enhances reactivity in coupling processes involving aryl and vinyl substrates, offering high selectivity and functional group tolerance. Commonly applied in the synthesis of complex organic molecules, including pharmaceuticals and fine chemicals, where efficient catalytic performance under mild conditions is required. The triflimide counterion improves solubility and stability, making it suitable for use in non-polar reaction media.
