Competitive retro‐cycloaddition reactions in heterocyclic fullerene bis‐adducts ions: selective removal of the heterocyclic moieties

Abstract

The observed selectivity in the heterocyclic removal in these [60]fullerene derivatives is reversed from negative conditions (radical anions) to positive conditions (protonated molecules). Moreover, the retro-cycloaddition reaction behaves differently under spectrometric and thermal conditions.
