7787-70-4,7787-70-4, Copper(I) bromide is a copper-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of CuBr (28.7mg, 0.2mmol) and dppp (82.5mg, 0.2mmol) with an excess of batho (66.5mg, 0.2mmol) were dissolved in CH2Cl2 (5mL) and CH3OH (5mL) solution, stirred at room temperature for 6h. The insoluble residues were removed by filtration, and the filtrate was evaporated slowly at room temperature to yield yellow crystalline products. Yield: 80%. Anal. Calc. for C53H50BrCuN2O2P2: C, 66.84; H, 5.29; N, 2.94. Found: C, 66.97; H, 5.15; N, 2.88%. IR (KBr disc, cm-1): 3378s, 3048w, 2858w, 2580w, 1616w, 1556m, 1515m, 1433s, 1414m, 1229m, 1026s, 998w, 767m, 740s, 698vs, 513s, 482m. 1H NMR (600MHz, CDCl3, 298K): delta 7.87-8.98 (d, 6H, batho CH), 7.56-7.68 (m, 10H, batho CH), 7.41-7.24 (m, 20H, dppp CH), 2.91-2.81 (m, 4H, CH2), 2.78-2.63 (m, 2H, CH2); 31P NMR (400MHz, CDCl3, 298K): -12.25, -14.84.
The synthetic route of 7787-70-4 has been constantly updated, and we look forward to future research findings.
