As a common heterocyclic compound, it belong copper-catalyst compound,Copper(I) bromide,7787-70-4,Molecular formula: BrCu,mainly used in chemical industry, its synthesis route is as follows.,7787-70-4

General procedure: HLBAP (0.525 g, 1 mmol) and triethylamine (0.28 mL, 2 mmol) were dissolved in a 2:1 acetonitrile/dichloromethane mixture (45 ml), and then copper salt with the corresponding anion (1 mmol) was added. The reaction mixture was stirred for 4 h at room temperature in the presence of air. X-ray quality red brown crystals were grown from a 1:1 solvent mixtureof dichloromethane/methanol.

With the synthetic route has been constantly updated, we look forward to future research findings about Copper(I) bromide,belong copper-catalyst compound

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.,7787-70-4

General procedure: Compound 5c was prepared as described for 5a. In this respect, 2 (100 mg, 0.160 mmol) was reacted with [CuBr] (3c) (23 mg, 0.160 mmol). Appropriate work-up, gave 5c (111 mg, 0.144 mmol, 90% based on 2) as a brown solid Mp.: 180 C. IR (KBr, cm-1): nuC?C 1983 (w). 1H NMR (d6-DMSO, delta): 0.24 (s, 9 H, SiMe3), 0.30 (s, 9 H, SiMe3), 7.61 (ddd, 3JH7H6 = 4.7 Hz, 3JH7H8 = 7.3 Hz; 1 H, H7), 7.95 (ddd, 3JH2H1 = 6.3 Hz, 3JH2H3 = 6.6 Hz; 1 H, H2), 8.07 (ddd, 4JH8H6 = 1.5 Hz, 3JH8H7 = 7.3 Hz, 3JH8H9 = 7.8 Hz; 1 H, H8), 8.43 (m, 4JH3H1 = 1.0 Hz, 3JH3H2 = 6.6 Hz; 3JH3H4 = 8.0 Hz, 3JH9H8 = 7.8 Hz; 2 H, H3, H9), 8.67 (dd, 3JH6H7 = 4.7 Hz, 4JH6H8 = 1.5 Hz, 1 H, H6), 8.85 (d, 3JH4H3 = 8.0 Hz, 1 H, H4), 9.05 (dd, 3JH1H2 = 6.3 Hz, 1 H, 4JH1H3 = 1.0 Hz, 1 H, H1), 9.95 (s, 1 H, H5), 10.06 (s, 1 H, H10). ESI-MS (m/z (rel. intens.) in thf: [M++Br] 687 (100), [M+-CuBr + K] 662 (25). Anal. Calc. for C24H28N4CuBrPtSi2 (767.21 g/mol): C, 37.57; H, 3.67; N, 7.30. Found: C, 37.68; H, 3.63; N, 6.92%.

As the paragraph descriping shows that 7787-70-4 is playing an increasingly important role.
