Toxikologische Informationen
Health EffectsContact with palladium may cause palladium sensitivity and allergy. Animal studies have shown that palladium may damage the liver and kidney. (L798)
Exposure RoutesOral (A21) ; inhalation (A21) ; dermal (A21)
Toxicity Summary
Due to their ability to form strong complexes with both inorganic and organic ligands, palladium ions can disturb cellular equilibria, replace other essential ions, and interact with functional groups of macromolecules, such as proteins or DNA. Palladium complexes binding to DNA and RNA leads to strand breakage. Palladium ions are able to inhibit most major cellular functions, including DNA and RNA synthesis. Palladium compounds have been shown to bind to and inhibit various enzymes, including creatine kinase and prolyl hydroxylase. (L798)

Pharmakologische Informationen
Metabolism/Metabolites
Palladium may be absorbed through oral, dermal, and inhalation exposure. Once in the body it distributes to the kidney, liver, spleen, lymph nodes, adrenal gland, lung and bone. Palladium's ability to form complexes allows it the bind to amino acids, proteins, DNA, and other macromolecules. Palladium and its metabolites are excreted in the urine and faeces. (A21)

Anwendungen
VerwendenAllylpalladium(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.
