Description

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.

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.

Palladium-catalyzed carbonylative Heck reaction of aryl bromides with vinyl ethers to 3-alkoxy alkenones and pyrazoles.

Chemistry (Weinheim an der Bergstrasse, Germany), 18(16), 4827-4831 (2012-03-17)

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.
