Descrizione generale

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.

Applicazioni

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.
