deoxyfluorination of carboxylic acids to afford various acyl fluorides. This all-carbon-based fluorination reagent enabled the efficient transformation of (hetero)aryl, alkyl, alkenyl, and alkynyl carboxylic acids to the corresponding acyl fluorides under the neutral conditions. This deoxyfluorination method was featured by the synthesis of acyl fluorides with in-situ formed CpFluor, as well as the one-pot

Trifluoromethyl copper (CuCF3), as a diverse fluorination reagent, has been widely used in trifluoromethylation, perfluoroalkylation, and difluorocarbene reactions. However, it has rarely been reported as a single fluorine source involved in nucleophilic fluorination reactions. This work describes a general strategy involving copper-mediated deoxyfluorination of redox-active esters to rapidly access
