The head‐to‐tail autocondensation of 4‐fluoroacetophenone in the KOH/DMSO superbase suspension stops on dimerization step affording 4‐acetylbenzyl‐4'‐fluorophenylketone. This new fluorine substitution (SNAr) reaction opens short and simple route to so far inaccessible aromatic diketones via the nucleophilicsubstitution of fluorine atom in 4‐fluoroacetophenone by available acylbenzenes.
