Several methyltetrahydrofurans have been studied in HSO 3 FSbF 5 SO 2 solution. O ‐Protonation was observed from 1 H NMR measurements at low temperature, and the coupling constants between + OH and the CH protons α to oxygen were measured from the CH signals. A conformational interpretation could be carried out from these results.
