Used as a catalyst in cross-coupling reactions, particularly in the formation of carbon-carbon bonds. It plays a key role in Ullmann-type reactions and other nickel-catalyzed coupling processes, offering an alternative to palladium-based systems. Its stability and reactivity make it suitable for transformations in organic synthesis, including aryl-aryl and aryl-heteroaryl bond formations. Commonly applied in the development of pharmaceuticals, agrochemicals, and advanced materials where efficient and selective coupling is required.
