Application
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.
General description
Palladium(II) bromide (PdBr2) is widely used as Pd(II) catalyst. PdBr2 can be prepared by reacting palladium metal with HNO3 and HBr. Electrosynthesis of PdBr2 from palladium metal and HBr has been reported.

Three COming together: The first carbonylative Heck coupling reaction of aryl bromides and vinyl ethers leading to 1-aryl-3-alkoxy-2-propen-1-ones has been established (see scheme). Based on this coupling methodology, a novel one-pot synthesis of aryl-substituted pyrazoles was also realized.
