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. 64248-58-4, name is 1,2-Difluoro-4-iodobenzene, This compound has unique chemical properties. The synthetic route is as follows., 64248-58-4
General procedure: A Schlenk flask equipped with asepta and a magnetic stir bar wasfilled with aryl halide (3.0 mmol), alkene (3.2 mmol), K2CO3(3.5 mmol) and PdLn-beta-CD 3 mol% catalyst in water (5 mL pure orplain). The reaction was refluxed for the appropriate time underaerobic conditions. After completion of the reaction was confirmedby TLC, the reaction mixturewas cooled to room temperature.The solvent was removed by rotary evaporator and extraction of theproduct was carried out using ethyl acetate. The ethyl acetate fractionwas separated and dried over anhydrous sodium sulphate. Theresulting crude product was purified using flash column chromatographyof silica gel 60-120mesh with n-hexane/ethyl acetate (8:2ratio) as the eluent and afforded the pure desired product. After extractionof product, catalyst was simply reprecipitated from theaqueous layer by the addition of 10 mL of acetone. The recoveredcatalyst was filtered, washed with acetone (3 ¡Á 5 mL) and dried ina vacuum at 70 C for 5 h and reused.
