α′‐Fluoro β‐boryl ketones can be efficiently synthesised from a sequential organocatalytic β‐boration pathway and consecutive electrophilic fluorination reaction in an acidic medium. Alternatively, the regioisomers of α‐fluoro β‐boryl ketones can be diastereoselectively obtained from Cu(I)‐mediated β‐boration followed by in situ fluorination of the boron enolate. Enantioenriched mixtures of the major
