Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 7787-70-4, name is Copper(I) bromide. This compound has unique chemical properties. The synthetic route is as follows. 7787-70-4
7787-70-4, General procedure: In a round bottom flask, copper(I) halide (0.1mmol, CuBr for 1 or CuI for 2) was dissolved in 2mL of MeCN. Under continuous stirring, a 5mL MeCN:EtOH (3:2) solution of HC(3-PhPz)3 (0.11mmol, 50mg) was added dropwise. The produced light brown solution was stirred at room temperature for 3h, then its volume was reduced by evaporation to ca. 2mL. Hexane (10mL) was added and the obtained precipitate was filtered off, recrystallized from a mixture of CH2Cl2 and hexane (1:1) to afford complexes 1 or 2 as colourless crystals. [CuBr(TpmPh)] (1): Yield (45.9mg) 78%. Elemental analysis calcd (%) for C28H22BrCuN6¡¤CH2Cl2: C 51.92, H 3.61, N 12.53; found: C 51.51, H 3.70, N 12.64. FTIR (KBr): nu (cm-1)=1532m, 1491 w, 1442m, 1391 w, 1342 w, 1324 w, 1299 w, 1268 w, 1242m, 1209m, 1095m, 1077m, 1038m, 798m, 756s, 688s. Far IR (CsI): nu (cm-1)=221m nu(Cu-Br). 1H NMR (300MHz, DMSO-d6, delta): 9.10 (s, 1H, HC(3-PhPz)3), 8.11 (br, 3H, 5-H-pz), 7.85 (br, 6H, o-H-Ph), 7.42 (br, 9H, m,p-H-Ph), 6.95 (br, 3H, 4-H-pz). 13C{1H} NMR (300MHz, DMSO-d6, delta): 152.14 (3-C-pz), 132.20 (Cquat-Ph), 131.82 (5-C-pz)), 128.76 (m-C-Ph), 128.32 (p-C-Ph), 125.53 (o-C-Ph), 104.57 (4-C-pz), 82.09 (HC(3-Phpz)3). ESI(+)MS in MeCN (m/z assignment, % intensity): 546 ({[HC(3-Phpz)3]Cu+MeCN}+, 100), 505 ({[HC(3-Phpz)3]Cu}+, 23).
