Description

Description générale

Cuprous bromide may be prepared by the reduction of cupric bromide or CuSO₄-NaBr. In the molten state, it is grayish brown /greenish brown in color.

Application

Some reported applications of copper bromide are:

• catalyst in cross coupling reactions.
• co-catalyst in Sonogashira coupling.
• Lewis acid in enantioselective addition of alkynes.
• reducing agent, when complexed by three molecules of pyridine initiators for the controlled polymerization of styrene, methyl acrylate and methyl methacrylate.

Reductive homocoupling of α-bromo- α- chlorocarboxylates to dimethyl α, α′ dichlorosuccinate derivatives in presence of CuBr/LiOCH3 in methanol has been reported.
