[1,3-Bis[2,6-di(propan-2-yl)phenyl]imidazol-2-ylidene]-triphenyl-λ⁵-phosphane;nickel(2+);dichloride(CAT: L002488) is a well-defined nickel(II) complex featuring an N-heterocyclic carbene (NHC) ligand and triphenylphosphine coordination. The bulky diisopropyl-substituted NHC provides strong σ-donation and steric shielding, enhancing the stability and catalytic activity of the nickel center. This complex is widely employed in homogeneous catalysis, particularly in cross-coupling reactions such as Kumada, Negishi, and Suzuki–Miyaura couplings. Its robust structure and tunable electronic properties make it ideal for the activation of aryl halides and challenging C–C bond formations. Additionally, the complex is useful in polymerization and fine chemical synthesis, offering high efficiency, air-stability, and selective performance in organometallic catalysis.
