Used as a highly efficient catalyst in organic synthesis, particularly in C–H bond activation and cross-coupling reactions. It enables selective transformations under mild conditions, making it valuable in pharmaceutical and fine chemical industries for constructing complex molecules. The gold center, stabilized by the bulky diisopropylbenzimidazolylidene ligand, exhibits strong catalytic activity with improved stability and turnover. Effective in alkyne functionalization and cyclization processes, it supports atom-economical and sustainable synthetic routes.
