Synthesis of Fluoroalkanes by Deoxygenative Hydrofluorination of Carbonyl Compounds via Their Tosylhydrazones

Typical Procedure:
A mixture of carbonyl compound (1 mmol) and tosylhydrazide (1 mmol) in toluene (4 mL) is stirred at 80 °C for 1.5 h in a round bottom flask fitted with a reflux condenser. Potassium carbonate (5.0 mmol) and Et3N•3HF (1.5 mmol) are added to the reaction mixture. The system is refluxed at 110 °C with stirring under a nitrogen atmosphere. After completion of the reaction, as monitored by TLC, the crude mixture is allowed to cool to room temperature. It is quenched with saturated aqueous sodium hydrogen carbonate (10 mL) and extracted with ethyl acetate (3 × 10 mL). The organic phase is dried over anhydrous magnesium sulfate and concentrated under reduced pressure to yield the crude product, which is purified by silica gel column chromatography (EtOAc―Hexane) to give the analytically pure desired product.
