• Description: Cupric bromide is a kind of inorganic compound obtained through the reaction between copper oxide and hydrobromic acid. It can be used in laser, generating pulse yellow and green light. The cupric bromide laser is an important technology used in dermatology for the treatment of pigmented lesion and vascular lesions. It can also be used in living radical polymerization and as an intensifier in photographic processing. It is also a brominating agent used in organic synthesis. In addition, it is a kind of highly efficient catalyst in the direct alkynylation of azoles.
• Uses: Copper(II) bromide is used as a catalyst in organic reactions, as an intensifier in photography, and as a brominating agent. As intensifier in photography; as brominating agent in organic synthesis; as humidity indicator; as wood preservative; in solid-electrolyte battery; as stabilizer for acetylated polyformaldehyde. Copper(II) bromide is used in photographic processing as an intensifier and as a brominating agent in organic synthesis. It is also used in the coupling of o-iodophenols and aryl acetylenes avoiding the use of palladium. It finds application in the preparation of NK1/NK2 receptor antagonists used in the regulation of tachykinin. 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.
