[Bis(diphenylphosphino)ethane]dichloronickel（Cat No.:R025455）, commonly abbreviated as NiCl₂(dppe), is a coordination complex featuring a nickel(II) center bonded to a bidentate bis(diphenylphosphino)ethane (dppe) ligand and two chloride ions. This square planar complex is widely used as a catalyst or catalyst precursor in organometallic and cross-coupling reactions, including carbon–carbon and carbon–heteroatom bond formations. The dppe ligand stabilizes the nickel center and tunes its electronic properties, making it valuable in homogeneous catalysis. Its well-defined structure and reactivity profile make it a versatile tool in synthetic and polymer chemistry applications.
