• Synthesis

  The synthesis of 4-IODOBUTYL ACETATE is as follows:Acetic acid (0.30mmol, 1.0 equivalent), CuI (0.03mmol, 10.0mol%, 5.7mg) and NaI (0.60mmol, 2.0 equivalent, 89.9mg) were added to a 10mL Schlenk tube equipped with a magnetic stirring device. Vacuum the flask with a pump and backfill it three times with nitrogen. Then, 1.0 mL tetrahydrofuran (12.30 mmol, 41.0 equivalence, 1 mL, c=0.30 M), deionized water (0.45 mmol, 1.5 equivalence) and TMSCF3 (0.36 mmol, 1.2 equivalence) were added under N2 atmosphere. The mixture is stirred at 150°C (thermostatic oil bath pot) for 12 hours. After cooling to room temperature, dilute the mixture with ethyl acetate (15 mL), wash with water and brine, and dry on anhydrousNa2SO4. After Extraction by EtOAc (5 mL x 3), the combined organic layer was dehydrated with anhydrousNa2SO4 and concentrated under reduced pressure. The crude product is purified by rapid chromatography on silica gel to obtain alkyl iodide.
