Widely used as a catalyst in cross-coupling reactions, particularly in organic synthesis for forming carbon-carbon bonds. It enables reactions such as Suzuki, Heck, and Negishi couplings, which are essential in pharmaceutical and agrochemical industries for constructing complex molecules. Its stability and reactivity make it suitable for catalyzing transformations under mild conditions, often with high selectivity and yield. Commonly employed in the synthesis of biaryl compounds, conjugated systems, and functionalized heterocycles used in drug development and materials science.
