1,3-DIBROMO-4-IODOBENZENE Use and Manufacturing
[Production Example 1]; The following Indenopyrene Compound A was produced through the following synthesis route.; Synthesis of Intermediate A1; 2, 4-Dibromoaniline (10 g, 40 mmoles) was suspended in hydrochloric acid water (40 mL of concentrated hydrochloric acid and 30 mL of water), and the suspension was cooled on an ice/salt bath at -8°C. A sodium nitrite aqueous solution (3.0 g, 43 mmoles, 1.1 eq. /15 mL) was gradually added dropwise thereto over 10 minutes, and the mixture was stirred at from -10°C to 0°C for 30 minutes, thereby preparing a diazonium salt. The reaction solution was gradually added dropwise to a potassium iodide aqueous solution (60 g, 0.36 moles, 9 eq. /180 mL) at room temperature over 20 minutes. The reaction mixture was stirred at room temperature for 3 hours, to which was then added dichloromethane (200 mL), and subsequently, sodium hydrogensulfite (2 g) was added, thereby deactivating generated iodine. An organic layer was aliquoted, washed with a sodium hydrogensulfite aqueous solution (100 mL) and saturated salt water (30 mL) and then dried over anhydrous magnesium sulfate, and the solvent was then distilled off to obtain a red liquid. This was purified by means of column chromatography (silica gel/hexane) to obtain a white solid (11.0 g, 76percent).
