Abstract Triflic acid (TfOH) has been proven to be effective as a tolerant acidic mediator in electrophilic aromatic aroylation with CF3‐bearing aroyl chlorides. The TfOH‐mediated aroylation of fluorobenzene proceeds with high selectivity to give CF3‐bearing aryl fluorophenyl ketones in good yields, which are hardly obtained with the aid of AlCl3 or direct condensation reagents.
