We would recommend using a metallic scavenger like the QuadraPureTM products. Product numbers 655422 and 657662 are designed to scavenge palladium ions and are effective in both acidic and basic conditions. The resins are capable of removing metallic contamination to very low levels and are ideal for pharmaceutical or fine chemical processing.

Descrição geral
Palladium(II) acetate is a homogenous oxidation catalyst. It participates in the activation of alkenic and aromatic compounds towards oxidative inter- and intramolecular nucleophilic reactions.[1] Crystals of palladium(II) acetate have a trimeric structure, having symmetry D3h. Each of the palladium atoms in the crystals are joined to the other two by double acetate bridges.[2] Microencapsulation of palladium(II) acetate in polyurea affords polyurea-encapsulated palladium(II) acetate. It is a versatile heterogeneous catalyst for various phosphine-free cross-coupling reactions.[3] It participates as catalyst in the Heck coupling reaction of pthalides with different alkenes.[4]
Aplicação
Palladium(II) acetate was employed as a catalyst for the following reactions:
For small scale and high throughput uses, product is also available as ChemBeads (924377)
- Formation of allylic acetates.[5] (eq. 1)

What is the difference between Product 520764, Palladium (II) acetate, and the palladium acetate in the form of a ChemDose® tablet?
1 answer-
The ChemDose® products offer a streamlined way to catalyze reactions. The catalyst is dispersed in an inert tablet matrix in specific millimolar and micromolar quantities. The tablets can decrease time spent on weighing/adding the catalyst to the reaction mixture. The tablets effectively give the same reaction yields with a controlled release of the catalyst. They are also extremely easy to remove after the reaction is complete. The inert tablet usually stays intact throughout the reaction. Product 684929 is the ChemDose® tablet that contains 2.0 μmol of palladium (II) acetate, while product#: 685593 is the 10μmol version.
