Tetrakis(Triphenylphosphine)Nickel

C72H60NiP4

CAS: 15133-82-1

Tetrakis(triphenylphosphine)nickel(0), chemical formula Ni(PPh₃)₄, is a bright yellow, air-sensitive coordination complex containing nickel in the zero oxidation state. As a versatile homogeneous catalyst, it plays a critical role in cross-coupling reactions, polymerization catalysis, and organonickel chemistry research. Its four triphenylphosphine ligands stabilize nickel(0), enabling high activity in C–C bond formation and other selective transformations.
