Application
TCI Practical Example: Fluorination of 1,3-Dicarbonyl Compound Using F-TEDA-BF4
-
Used Chemicals
-
Procedure
-
To a solution of acetoacetanilide (194 mg, 1.1 mmol) in acetonitrile and water (1:1, 4 mL) was added F-TEDA-BF4 (778 mg, 2.2 mmol). The reaction mixture was stirred at r.t. for 24 hours. Then solvent was removed under reduced pressure and the residue was purified by column chromatography (ethyl acetate:hexane = 0:1 - 1:9 on silica gel) to give 2,2-difluoro-3-oxo-N-phenylbutanamide as a light yellow liquid (214 mg，y. 92%).

Application
Metal-Free Fluorination of C(sp3)-H Bonds using a Catalytic N-Oxyl Radical
Typical Procedure: To a solution of 4-phenylbutyl benzoate (55.6 mg, 0.219 mmol) and NDHPI (1.36 mg, 0.00547 mmol) in MeCN (2.2 mL) is added F-TEDA-BF4 (155 mg, 0.438 mmol) at room temperature. The mixture is degassed by freeze-thaw for 3 times under Ar atmosphere, and stirred at 50 °C for 5 h. The reaction mixture is then neutralized with saturated aqueous NaHCO3, and extracted with EtOAc (3 mL×3). The combined organic layers are dried over Na2SO4, and concentrated. The residue is purified with flash column chromatography (silica gel, hexane : Et2O=30 : 1) to provide 4-benzoyloxy-1-phenylbutyl fluoride (43.1 mg, Y. 72%).

Application
Regiospecific fluorination of functionalized phenols
Typical procedue: To 4-(biphenyl)tributylstananne (44.3 mg) in acetone (2.0 mL) at 23°C is added silver triflate (51.4 mg) and N-fluoro-N'-(chloromethyl)triethylenediamine bis(tetrafluoroborate) (F-TEDA-BF4) (42.5 mg). The reaction mixture is stirred for 20 min at 23°C and then concentrated in vacuo. The residue is purified by preparative TLC eluting with hexane to give 12.0 mg of the fluorinated compound as colorless solid (70% yield).
