enone-α-H to F substitution, leading to 2-fluoroenones in a single step from ubiquitous enones in 63–90% yield. The reaction is applicable to a wide range of aromatic and alkenyl enones and is carried out at room temperature using HF-pyridine complex as the fluoride source. Mechanistic investigations support that the reaction takes place through a rare umpolung Morita–Baylis–Hillman-type mechanism.
