Widely used as a catalyst in cross-coupling reactions, particularly in the formation of carbon-carbon and carbon-heteroatom bonds. It exhibits high efficiency in Suzuki-Miyaura and Buchwald-Hartwig amination reactions, enabling the synthesis of biaryls and functionalized amines under mild conditions. Its phosphine-based ligand system enhances stability and reactivity, making it suitable for transformations involving aryl chlorides, which are typically less reactive. Commonly applied in pharmaceutical and agrochemical synthesis where selective and efficient coupling is required. Also employed in materials science for constructing conjugated organic frameworks used in optoelectronic devices.
