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. 27139-97-5, name is 2-Bromo-4-chloro-1-methylbenzene, This compound has unique chemical properties. The synthetic route is as follows., Application In Synthesis of 2-Bromo-4-chloro-1-methylbenzene
In a three-necked round-bottom 500 ml flask equipped with a reflux condenser, thermometer, dropping funnel with pressure-equalizing, and magnetic stirring bar, 41.3 ml (128 g, 0.80 mmol) of bromine were added dropwise to 164 g (0.80 mol) of 2-bromo-4-chlorotoluene under exposure to 500 W lamp for 3 h at 19O0C. The resulting mixture was cooled to room temperature. Fractional distillation gave a colorless liquid, b.p. 1 1 1-1 15C/7 mm Hg. Yield 182 g (80%).Anal. calc. for C7H5Br2Cl: C, 29.56; H, 1.77. Found: C, 29.76; H, 1.89.1H NMR (CDCl3): delta 7.44 (d, J= 1.7 Hz, IH, 2-H), 7.36 (dd, J= 6.0 Hz, J= 1.7 Hz, IH, 4-H), 7.18 (d, J= 6.0 Hz, IH, 5-H), 4.69 (s, 2H, CH2).
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 27139-97-5.
