3) Preparation of Tetrakis(triphenylphosphine)palladium

Tetrakis(triphenylphosphine)palladium(0) was first prepared by Lamberto Malatesta and his group in Milan in the 1960s by reduction of sodium chloropalladate with hydrazine in the presence of the phosphine.[2] It is commercially available, but can be prepared in two steps from Pd(II) precursors:

PdCl₂ + 2 PPh₃ → cis-PdCl₂(PPh₃)₂
cis-PdCl₂(PPh₃)₂ + 2 PPh₃ + 2.5 N₂H₄ → Pd(PPh₃)₄ + 0.5 N₂ + 2 N₂H₅+Cl^-

4) Uses of Tetrakis(triphenylphosphine)palladium

Pd(PPh₃)₄ is widely used as a catalyst for palladium-catalyzed coupling reactions, such as Pd(PPh₃)₄ + ArBr → PdBr(Ar)(PPh₃)₂ + 2 PPh₃. Prominent applications include the Heck reaction, Suzuki coupling, Stille coupling, Sonogashira coupling, and Negishi coupling.
