of a deoxyfluorination protocol using sulfur tetrafluoride (SF4) as a reagent to prepare organofluorine compounds in continuous flow mode. The method uses mild conditions, without the use of HF, which provides an improved safety profile. The methodology was applied to successfully convert various alcohols, aldehydes, and carboxylic acids to their corresponding fluorinated compounds. Advantages of the
