7411-23-6, Adding some certain compound to certain chemical reactions, such as: 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 7411-23-6.
2,2′-Bipyridine (3.12, 20 mmol), copper acetate (3.63 g, 20 mmol) and sodium carbonate (4.24 g, 40 mmol) was added to a solution of 3,5-dibromo-1H-1,2,4-triazole (4.54 g, 20 mmol) and cyclopropyl boronic acid (3.44 g, 40 mol) in DCE (150 ml). The r.m. was heated at 70 C. for 16 h and was then cooled to r.t. and washed with a sat. aq. solution of ammonium chloride. The combined organic extracts were washed with brine and dried (MgSO4). Filtration and concentration under reduced pressure gave a residue which was purified by flash column chromatography over silica gel (eluent: Heptane/EtOAc from 100/0 to 50/50). The product fractions were collected and concentrated in vacuo, yielding 1 g of a 70/30 mixture of intermediate 69 and intermediate 70 (21%) which was used as such in the next reaction step.
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 7411-23-6.
