Substrate scope for the for the pentafluorosulfanylation of 1 and 2 and XRD structure of product 9. Yields were determined by ¹⁹F‐NMR spectroscopy in the crude reaction mixture. General reaction conditions: 0.20 mmol, 0.20 m in MeCN, 10 mol % 3, 10 mol % BEt₃, 22 h, 20 °C, 2.8 bar (15 equiv) SF₆, 368 nm. [a] Yield determined by GC‐FID, 20 mol % BEt₃ used. [b] 3.0 equiv alkynol. [c] 0.15 m, 14 equiv. allene. [d] 1.00 mmol scale. [e] Prepared with 1‐ethinyl‐1‐cyclopentanol.
