General description

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

Application

Some applications of copper bromide reported are as a :
  • 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.
