Potassium fluoride (KF) is an ideal reagent for fluorination because it is safe, easy to handle and low-cost. However, poor solubility in organic solvents coupled with limited strategies to control its reactivity has discouraged its use for asymmetric C-F bond formation. Here, we demonstrate that hydrogenbonding phase-transfer catalysis with KF provides access to valuable β-fluoroamines in high yields
