This gold(I) N-heterocyclic carbene complex serves as an effective catalyst in organic synthesis, particularly for activating π-systems such as alkynes and allenes to promote reactions including cycloisomerizations, hydrofunctionalizations, and the formation of carbon-carbon and carbon-heteroatom bonds. Its air- and moisture-stable structure enables efficient catalysis under mild conditions, making it ideal for the synthesis of pharmaceuticals, natural products, and fine chemicals. Applications also include materials science, where it facilitates controlled polymerization processes for advanced materials.
