In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 4101-68-2 as follows. name: 1,10-Dibromodecan
2.2.4 9-(10-bromodecyl)-9H-carbazole (4) Under argon atmosphere, carbazole (1.67 g, 0.01 mol), anhydrous potassium carbonate (2.77 g, 0.02 mol), and 1,10-dibromodecane (6.00 g, 0.02 mol) in 40 mL of anhydrous acetonitrile were refluxed at 95 C for 36 h. After cooling to room temperature, insoluble substance was filtered, and the solvent was removed under reduced pressure. The crude product was purified by column chromatography on silica gel with petroleum to get 9-(10-bromodecyl)-9H-carbazole as white crystals (1.66 g, Yield 43%). 1H NMR (500 MHz, CDCl3, delta): 8.08 (d, J = 7.7 Hz, 2H, Ar-H), 7.43 (t, J = 7.8 Hz, 2H, Ar-H), 7.35 (d, J = 8.1 Hz, 2H, Ar-H), 7.20 (t, J = 7.5 Hz, 2H, Ar-H), 4.21 (t, J = 7.3 Hz, 2H, CH2), 3.33 (t, J = 6.8 Hz, 2H, CH2Br), 1.79 (m, 4H, CH2), 1.33-0.91 (m, 12H, CH2). FT-IR (cm-1, KBr): 2930, 2850 (s; CH), 1632, 1619, 1593 (m; Ar). Anal. Calcd. For C22H28BrN: C, 68.39; H, 7.30; N, 3.63; Found: C, 68.47; H, 7.25; N, 3.56.
According to the analysis of related databases, 4101-68-2, the application of this compound in the production field has become more and more popular.
