The regiochemistry of the hydrofluorination of terminal epoxides with Olah's reagent (Py·9HF) is dependent on the electron-withdrawing character of the β-substituents. Phenoxy ethers with different substitution patterns of the aromatic ring and several N-heterocycles were examined as β-substituents.
