Used in organic synthesis as a catalyst for various reactions, particularly in the formation of carbon-carbon and carbon-heteroatom bonds. It is effective in gold-catalyzed cyclization processes, enabling the synthesis of complex cyclic structures. Applied in the preparation of pharmaceuticals and fine chemicals, where it facilitates selective transformations. Also employed in materials science for the development of gold-containing polymers and coatings. Its stability and reactivity make it valuable in advanced research and industrial applications.
