Anodic oxidation of [CB11H12](-) and 18 of its halogenated and/or methylated derivatives was examined. Reversible oxidation was found for four of the anions in liquid SO2 and for four more in 1,1,1,3,3,3-hexafluoroisopropyl alcohol. The oxidation occurred at similar to 1 V (for [CB11Me12](-)) up to more than 4 V (for [1-H-(2-6)-F-5-(7-12)-(CF3)(6)-CB11](-)) relative to ferrocene/ferricinium. The anodic peak potentials are reproduced by a set of additive position-sensitive substituent increments.
