General description

Copper bromide is a monoclinic crystalline material. It is soluble in water, alcohol and acetone. It may be synthesized by neutralizing oxides, carbonates or hydroxides of copper with hydrobromic acid. Another synthesis technique is by oxidizing copper either with bromine water or bromine solutions in alcohol.

Application

Copper bromide may be used as a catalyst in organic reactions and as a brominating agent. Copper catalyzed biotinylation of acetylene terminated poly(ethylene glycol) methyl ether methylacrylate (PEGMEMA) chains has been investigated. Copper dibromide in acetonitrile acts as a catalyst in the interconversion of acetals to bis(methoxyphenyl)methyl (BMPM) ethers. It has been used as a catalyst in the intramolecular decarboxylative functionalization of α-carbonyl to yield a C(sp(3))-O bond for the synthesis of furo[3,2-c]coumarins. Poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) has been reportedly doped with CuBr2 to act as hole transport layer (HTL) in polymer solar cells(PSCs). Doping increase the conductivity and thereby increasing the device power conversion efficiency of PSCs.
