XtalFluor-E promotes a deoxofluorination reaction of carboxylic acids to provide a wide range of acyl fluorides in good yields after a simple filtration through a pad of silica gel. This transformation is assisted by a catalytic amount of NaF and occurs at room temperature in EtOAc. A sequential deoxofluorination/amidation is also possible.
