Used as a catalyst precursor in organic synthesis, particularly in cross-coupling reactions such as Kumada and Negishi couplings. It is effective in facilitating carbon-carbon bond formation under mild conditions. The dimethoxyethane ligand stabilizes the nickel center, enhancing solubility in organic solvents and improving reactivity. Commonly employed in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals. Also used in electroplating baths where controlled nickel deposition is required. Its adduct structure makes it easier to handle and store compared to anhydrous nickel chloride.
