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. 1996-29-8, name is 1-Bromo-4-chloro-2-fluorobenzene, This compound has unique chemical properties. The synthetic route is as follows., Safety of 1-Bromo-4-chloro-2-fluorobenzene
Carbazole (20.0 g, 119.6 mmol) and KF-alumina (30.0 g, 179.4 mmol) under a stream of nitrogenAnd 18-crown-6 (6.3 g) was placed in 120 mL of dimethyl sulfoxide (DMSO; Dimethylsulfoxide) solvent and stirred with heating.1-Bromo-4-chloro-2-fluorobenzene (25.1 g, 119.6 mmol) was added under reflux.After stirring for 8 hours, it was cooled to normal temperature, and the resulting solid was filtered to obtain a compound of the formula 2-2-A (35.1 g, yield 83%).
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 1996-29-8.
