Some common heterocyclic compound, 64115-88-4, name is 1-Bromo-2-(trifluoromethoxy)benzene, molecular formula is C7H4BrF3O, 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. 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).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 64115-88-4, its application will become more common.

Preparation of (2-[trifluoromethoxylphenyl)fphenyl)phosphine chloride To a flame dried Schlenk tube containing magnesium turnings (0.15 g, 6.22 mmo) in anhydrous THF (7 mi) was added 1-bromo-2- [trifluoromethoxy] benzene (1.0 g, 4.14 mmo). An exothermic reaction ensued. Stirring was continued at room temperature. Once the reaction exotherm had dissipated, the reaction mixture was used in the next step as described beiow: The Grignard reagent (separated from excess Mg) was incrementally added to a solution of PhPCI2 (0.74 g, 4.14 mmol) in anhydrous THF (10 ml) at -78C. Once addition was complete, the reaction was stirred at room temperature for a further 20 min after which the reaction was complete as judged by 3 P NMR ( 1P NMR (CDCIs): delta 72.27 (m); 61.81 (m)). The product was used in the next step without further purification.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 64115-88-4, its application will become more common.
