7787-70-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Copper(I) bromide, cas is 7787-70-4,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
A solution of CuBr (0.0173 g, 0.12 mmol) in 10 mL of acetonitrile was added dropwise to a solution of 4 (0.048 g, 0.12 mmol) in 10 mL of dichloromethane at room temperature. The reaction mixture was stirred for 4 h. The solvent was removed under reduced pressure to obtain 8 as a brown crystalline solid. Yield: 82% (0.054 g). Mp: >195 C (dec). Anal. Calc. for C42H44Cu2Br2N2P2Se2¡¤CH3CN: C, 46.99; H, 4.21; N, 3.74. Found: C, 46.77; H, 4.10; N, 3.79%. 1H NMR (400 MHz, CDCl3) delta 7.73-7.02 (m, Ar, 28H), 3.43 (s, CH2, 4H), 2.46 (s, NMe2, 12H). 31P{1H} NMR (162 MHz, CDCl3): delta 23.2 (br s).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Copper(I) bromide, 7787-70-4
