Used as a catalyst in cross-coupling reactions, particularly in the formation of carbon-carbon and carbon-heteroatom bonds. It facilitates reactions such as Ullmann-type couplings and other nickel-mediated transformations, offering an alternative to palladium-based systems in certain organic syntheses. Its pyridine ligands enhance solubility and stability, making it suitable for use in homogeneous catalysis. Also employed in research settings for the development of new synthetic methodologies and in the preparation of functionalized aromatic and heteroaromatic compounds.
