Description

General description

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.

Application

Application Guide for Palladium Catalyzed Cross-Coupling Reactions

Used in the synthesis of semiconducting metal-containing polymers in which the polypyrrole backbone has a conformational energy minimum and is nearly planar.

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

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

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