A near-stoichiometric amount of N-Formylsaccharin, an easily accessible crystalline compound, has been employed as an efficient CO source in a mild Pd-catalyzed fluorocarbonylation of aryl halides to afford the corresponding acyl fluorides in high yields. The acyl fluorides obtained could be readily transformed into various carboxylic acid derivatives such as carboxylic acid, esters, thioesters, and amides in a one-pot procedure.
