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. 626-39-1, name is 1,3,5-Tribromobenzene, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 626-39-1
n-Butyllithium (2.5 mL of a 2.5 mol/l solution in n-hexane,6.3 mmol) was added to a solution of 1,3,5-tribromobenzene (7) (2.00 g, 6.35 mmol) in Et2O (40mL) at -78 C under inert atmosphere. After 10 min, CuCN (282 mg, 3.18 mmol) was added andthe reaction mixture was allowed to warm up to -60 C within 90 min. Nitrobenzene (0.98 mL,9.53 mmol) was then added in one portion and the dark solution stirred while warming toambient temperature (16 h). An aqueous solution of NH3 (12.5% w/w, 80 mL) was slowly addedand the resulting mixture was extracted with MTBE (3 x 50 mL). The combined organic layerswere washed with water (50 mL) and brine (50 mL), dried over MgSO4, filtered and the solventwas removed in vacuum. Further purification was accomplished by column chromatography(SiO2, n-hexane, Rf 0.69). The resulting material was washed with acetone (20 mL) to give theproduct 8 as a colorless solid (722 mg, 1.54 mmol, 48%), mp 190 C (ref.22 190-191 C). 1HNMR (500 MHz, CDCl3): delta 7.70 (t, J 1.7 Hz, 2 H), 7.59 (d, J 1.7 Hz, 4 H) ppm. 13C{1H} NMR(126 MHz, CDCl3): delta 141.8 (2 C), 133.9 (2 CH), 129.0 (4 CH), 123.6 (4 C) ppm. IR (ATR):3103 (w), 3068 (m), 1579 (m), 1541 (s), 1407 (m), 1387 (m), 1098 (m), 1068 (m), 847 (s), 752(s), 672 (m), 653 (m) cm-1. MS (EI, 70 eV), m/z (%): 466 (95) [M+], 308 (25), 150 (25), 84(100). Anal. calcd. for C12H6Br4 (469.80): C 30.68, H 1.29; found C 30.68, H 1.30.
