Applicazioni

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-eta<sup>3</sup>-allyl chloride complex, which is an efficient catalyst for the Suzuki-Miyaura cross-coupling reactions in synthetic chemistry.

Note

Air and moisture sensitive. Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.
