Copper(I) bromide
Product Information
Molecular Formula
CuBr
Molecular Weight
143.45
Description
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.
