Tetrakis(triphenylphosphine)palladium  (Synonyms: Tetrakis(triphenylphosphine)palladium(0))

Tetrakis(triphenylphosphine)palladium is a catalyst. Tetrakis(triphenylphosphine)palladium catalyzes the highly regioselective addition of phenyl thiocyanate (PhSCN) to terminal alkynes^[1].

Tetrakis(triphenylphosphine)palladium is a classical catalyst precursor for certain cross-coupling reactions, notably including Negishi and early Suzuki couplings^[1].
Tetrakis(triphenylphosphine)palladium is a commonly used palladium (0) complex in chemical synthesis^[1].
