Globe‐trotting Hydrogens on the Surface of the Fullerene Compound C₆₀H₆(N(CH₂CH₂)₂O)₆

The [1,5] sigmatropic migration of hydrogen in the adduct between buckminsterfullerene C 60 and morpholine (Hmorph) is fast at −25°C already. Elemental analysis, thermogravimetry, IR and NMR spectroscopy, and cyclic voltammetry all support the formulation of the adduct as C 60 H 6 (morph) 6 . The amine is covalently added to six pyracylene units. The small activation barrier to the migration is astounding, especially as large changes in the C 60 framework are involved.
