Useful:

• Canonical SMILES: [Br-].[Br-].[Pd+2]
• Uses: Palladium (II) Bromide is pallidium coordination complex. Plalladium complexes are used as catalyst in Suzuki- Miyaura couplin reactions. Palladium(II) bromide (PdBr2) has been used as a source of Pd(0) precatalyst in various coupling reactions. It was also employed as catalyst for the carbonylative Heck coupling reaction of aryl bromides and vinyl ethers.
