These common heterocyclic compound, 64115-88-4, name is 1-Bromo-2-(trifluoromethoxy)benzene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 64115-88-4
2.0 g of 1~bromo-2-(trifluoro-methoxy)benzene (8.3 mmol) were dissolved in 30 ml of dichloromethane. At 0-50C, 1.06 g of chlorosulfonic acid (9.13 mmol), dis? solved in 3 ml of dichloromethane, were added dropwise. The reaction mixture was stirred for 30 min at room temperature. Additional 5.5 equivalents of chloro? sulfonic in dichloromethane were added to drive the reaction to completion. Standard work-up was followed and silica gel chromatography with n-heptane- dichloromethane (6:4) as eluent gave 2.19 g of the title compound.1H-NMR (CDCI3, 400 MHz): delta [ppm] 8.3 (d, 1 H), 8.05 (dd, 1 H), 7.5 (dd, 1 H).
The synthetic route of 1-Bromo-2-(trifluoromethoxy)benzene has been constantly updated, and we look forward to future research findings.
