    • 8]THF (≈ 0.5 mL) was distilled from a reservoir into the tube. The sample was degassed under vacuum by the freeze-pump-thaw technique and flame-sealed. For lithium samples the same procedure was conducted, except that a freshly produced lithium wire was immediately inserted into the upper part of an extended NMR tube. For several of the lithium samples, a small amount of corannulene was previously added to the tube. Controlled reductions of the samples were carried out by inverting the tubes at low temperature (-30°C) to bring the solutions into contact with the alkali metals. Returning the tubes to their upright positions stopped reductions from progressing.

    • This tetrameric model was found computationally to be an energy minimum. Unfortunately, semiempirical methods, as implemented in Spartan02 (AM1, PM3, and MNDO) do not handle potassium, and the system is too large to calculate with even higher levels of theory (e.g., ab initio and DFT).
