The pentafluorosulfanyl group has been proposed as a valuable addition to the toolbox of organofluorine chemistry. Here, we introduce commercially available (triisopropylsilyl)acetylene sulfur pentafluoride (TASP) as a versatile reagent that provides very low-risk access to the elusive class of α-SF₅ aldehyde enamines under benchtop conditions. This approach allowed these precious building blocks to be accessed and fully characterized for the first time.
