With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.7787-70-4,Copper(I) bromide,as a common compound, the synthetic route is as follows.
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).
7787-70-4 Copper(I) bromide 24593, acopper-catalyst compound, is more and more widely used in various.
