Palladium (II) Acetate Usage And Synthesis
  • Reactions
    1. Efficient catalyst for the arylation of olefins (Heck reaction).
    2. Catalyst for cross-coupling reactions.
    3. Catalyst for C-H activation.
    4. Precatalyst for enantioselective decarboxylative protonation of allyl β-ketoesters. 
  • Chemical Propertiesbrown needles
  • Usessuzuki reaction
  • UsesPalladium (II) Acetate Trimer is used in Suzuki-Miyaura cross-coupling reactions. It also serves to catalyze the chemoselective reduction of nitroarenes.
  • UsesA catalyst for intramolecular coupling.
  • Safety ProfileModerately toxic by ingestion. When heated to decomposition it emits toxic vapors of palladium.
  • Purification MethodsIt recrystallises from CHCl3 as purple crystals. It can be washed with AcOH and H2O and dried in air. Large crystals are obtained by dissolving it in *C6H6, adding half its volume of AcOH and allowing it to evaporate slowly at room temperature. It forms green adducts with nitrogen donors, it dissolves in KI solution to form solid PdI2 and a red solution of PdI42-, but is insoluble in aqueous saturated NaCl, and NaOAc. It dissolves in HCl to form PdCl42-. It is soluble in CHCl3, CH2Cl2, Me2CO, MeCN, Et2O, but it is insoluble in H2O, and decomposes when warmed in alcohols in which it is also insoluble.
