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

A designed ligand-accelerated Cu(I)-catalyzed cycloaddition (CuAAC) reaction was monitored for the first time by real time infrared analysis technique based on ATR-FTIR principles. Principal components analysis (PCA) and two-dimensional correlation spectroscopy (2Dcos) results showed that the consumption of alkyne and
