• Verwenden

  Allylpalladium(II) chloride dimer is used as an important catalyst in Heck reaction. It reacts with cyclopentadienyl anion to give cyclopentadienyl allyl palladium. It acts as a precatalyst for asymmetric and cross-coupling catalysis. Further, it is used in the preparation of 1,4-diallyl-1,2-dihydroisoquinolines. It is also employed as a catalyst for greener Buchwald-Hartwig coupling reaction and involved in the synthesis of cationic palladium catalysts. In addition, it takes part in preparation of -heterocyclic carbene-palladium-eta3-allyl chloride complex, which is an efficient catalyst for the Suzuki-Miyaura cross-coupling reactions in synthetic chemistry.

• synthetische

  Allylpalladium(II) chloride dimer is prepared by purging carbon monoxide through a methanolic aqueous solution of palladium(II) chloride, sodium chloride, and allyl chloride.
  2Na2PdCl4 + 2 CH2=CHCH2Cl + 2 CO + 2 H2O → (C3H5)2Pd2Cl2 + 4 NaCl + 2 CO2 + 4 HCl

• Reaktionen

  1. Precatalyst for the enantioselective hydrosilylation of olefins.
  2. Precatalyst for asymmetric allylic alkylation and amination.
  3. Used as a palladium source for cross-coupling reactions.
