What reactions are Product 520764, Palladium (II) acetate, used in?
Palladium (II) acetate is used as a catalyst for a number of reactions, including: Suzuki coupling reactions, (See ChemFiles 2.1 and ChemFiles 4.2) vinylation, (i.e. the Heck Reaction), rearrangement of acyclic dienes (i.e. the Cope Reaction).Papers that cite the use of this reagent are listed below. 1. B.M. Trost Tet. 33, 2615, (1977)2. R.F. Heck Acc. Chem. Res. 12, 146, (1979)3. Tet. 62, 9002, (2006)4. Org. Lett. 8, 3311, (2006) abstract5. Organometallic News 2, 52, (2002)
What is Product 520764, Palladium (II) acetate, soluble in?
Palladium acetate is not water-soluble; it is organic soluble. Although Sigma-Aldrich does not test solubility of 520764 directly, it is expected to be soluble in most common organic solvents, like chloroform, methylene chloride and acetone, according to the manufacturer.
When using are Product 520764, Palladium (II) acetate, what can I use to remove traces of palladium that this catalyst may leave behind?
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.
What is the difference between Product 520764, Palladium (II) acetate, and the palladium acetate in the form of a ChemDose® tablet?
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. More information on these products can be found at the link below.
What atmosphere is Product 520764, Palladium (II) acetate, packaged under?
This material is packaged under a layer of nitrogen to reduce the chance of moisture contamination.
