Widely used in homogeneous catalysis, this gold complex is particularly effective in promoting carbon-carbon bond-forming reactions, such as cycloisomerizations and hydroarylations. It exhibits high activity at low catalyst loadings, making it valuable in synthetic organic chemistry for constructing complex molecular frameworks. The robust N-heterocyclic carbene ligand enhances stability and prevents decomposition, allowing the catalyst to perform under mild conditions. It is also employed in reactions involving alkynes and allenes, where it facilitates selective transformations with excellent yields. Due to its air and moisture tolerance in many cases, it offers practical advantages in laboratory and industrial settings where strict inert conditions are challenging.
