In 2019,Chemistry Research Journal included an article by Gomaa, Esam A.; Mahmoud, Mahmoud H.; El-Hady, Mahmoud N. Abd; Elfarhaty, Yasmeen. Y.. Formula: Br2Cu. The article was titled 《Interaction of CuBr2 with succinic acid in KCl solution (cyclic voltammetry) using glassy carbon working electrode (GWE)》. The information in the text is summarized as follows:
The electrochem. behavior was studied for CuBr2 in the absence and presence of Succinic acid (SuA) sep. in 0.1M KCl solution The Glassy carbon electrode was prepared in our laboratory, which used as working electrode for measuring the voltammograms of CuBr2 in 0.1M KCl at 18.7°C. Stability constant and Gibbs free energy of interaction for CuBr2 + Succinic acid was done and their values were discussed. The experimental part of the paper was very detailed, including the reaction process of Cupric bromide(cas: 7789-45-9Formula: Br2Cu)
Some reported applications of Cupric bromide(cas: 7789-45-9) are: catalyst in cross coupling reactions; co-catalyst in Sonogashira coupling; lewis acid in enantioselective addition of alkynes.Formula: Br2Cu
