Beschreibung

Allgemeine Beschreibung

Palladium(II) chloride is used as a precursor to prepare palladium catalysts for various reactions like Heck coupling, cascade reaction, Buchward-Hartwig coupling. It is also used as an oxidizing agent.[1]

Anwendung

Anwendungsanleitung für palladium-katalysierte Kreuzkupplungsreaktionen

Verwendung bei der Synthese von halbleitenden, metallhaltigen Polymeren, in denen das Polypyrrol-Rückgrat ein Konformationsenergie-Minimum aufweist und dieses nahezu eben ist.

Palladium(II) chloride can be used as a catalyst in:

• Carbonylation of ketones to yield diesters.[2]
• Homo-coupling of aryl bromides using ascorbic acid and EDTA..[3]
• Acetylation of alcohols with vinyl acetate.[4]
• Arylation of 2-furaldehyde to yield 5-aryl-2-formylfuran derivatives.[5]

Pd precursor used as an oxidizing agent and as a source of Pd(0) complexes, e.g. Heck coupling, Cascade reaction, Buchward-Hartwig coupling.
