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. 892845-59-9, name is 1-Bromo-2-chloro-4-(trifluoromethoxy)benzene, This compound has unique chemical properties. The synthetic route is as follows., HPLC of Formula: C7H3BrClF3O
1-bromo-2-chloro-4-(trifluoromethoxy)benzene (0.25 g, 0.91 mmol) was added to an flame dried 50 mL round-bottomed flask charged with a stir bar containing tetrahydrofuran (4.0 mL). The solution was placed under Ar2, cooled to -78 C. and n-butyllithium in hexanes (1.1 M, 0.83 mL) was added dropwise. The reaction proceeded for 5 min at -78 C. and then was quickly poured over dry ice. The solvents were evaporated in vacuo and the subsequent oil was partitioned between H2O and hexanes. The aqueous was washed with hexanes (3*10 mL) and then the aqueous was acidified with 1N HCl (10 mL). The product was extracted with EtOAc (3*20 mL), washed with brine (3*10 mL), dried over MgSO4, and concentrated in vacuo. 1H NMR (500 MHz, CDCl3-d) delta ppm 8.11 (d, J=8.7 Hz, 1H) 7.39 (d, J=1.7 Hz, 1H) 7.22 (dd, J=8.8, 1.7 Hz, 1H); HPLC Ret: 6.65 min.
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 892845-59-9.
