101335-11-9, 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. 101335-11-9, name is 2-Chloro-4-fluoro-1-iodobenzene, This compound has unique chemical properties. The synthetic route is as follows.
To a solution of 2-chloro-4-fluoro-l-iodobenzene (10.0 g, 39.0 mmol) in dry THF (150 niL) was added /-PrMgCl (29.3 niL, 2.0 N, 58.5 mmol) dropwise at 0 C . After stirring for 1 hr at 0 C , the reaction was warmed to room temperature and stirred for 2 h. 1,4-cyclohexanedione monoethylene acetal (4.87 g, 31.2 mmol) was added and the reaction was stirred at room temperature for 12 h. Water (100 mL) was added and the mixture was extracted with ethyl acetate (3 x 100 mL). The combined organic phases were washed with brine (100 mL), then dried over Na2SO4. After concentration in vacuo, the crude material was purified by column chromatography (petroleum ethe?ethyl acetate = 5:1) on silica gel to give the desired product as a white solid (5.38 g, 48%). 1H NMR (400 MHz, CDCl3): delta 7.61-7.57 (m, IH), 7.14-7.11 (m, IH), 6.99- 6.94 (m, IH), 4.00-3.95 (m, AzU), 2.63-2.57 (m, IH), 2.42-2.36 (m, 2H), 2.17-2.10 (m, 2H), 2.05-2.01 (m, 2H), 1.72-1.69 (m, 2H).
