Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 147808-02-4, name is 2-Fluoro-1,4-diiodobenzene, A new synthetic method of this compound is introduced below., Computed Properties of C6H3FI2
Step 1-A: A solution of 2-fluoro-1,4-diiodo-benzene (804 mg, 2.31 mmol) in tetrahydrofuran (8 mL) was cooled to -78 C. (external) and a 2.0 M solution of isopropylmagnesium chloride in tetrahydrofuran (1.44 mL, 2.89 mmol) added via syringe. The resulting mixture was stirred for 30 minutes while allowing the temperature of the cooling bath to rise to -50 C. The reaction mixture was then immersed in an ice/water bath and anhydrous N,N-dimethylformamide (425 muL, 5.78 mmol) was added by syringe to the reaction mixture. The reaction was stirred at 0 C. for 10 minutes, then at room temperature for 5 minutes. Thin layer chromatography (TLC) indicated the reaction to be complete. The mixture was diluted with saturated aqueous ammonium chloride solution (8 mL) and extracted with diethylether (2*20 mL). The combined organic layers were dried over sodium sulfate and concentrated in vacuo. The resulting residue was purified by chromatography over silica gel gradient eluted with 0 to 15% v/v ethyl acetate/hexanes to give 2-fluoro-4-iodo-benzaldehyde as a fluffy-white solid (389 mg, 67%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
