A 14‐membered heterocycle is created on the C60 cage skeleton through a multistep procedure. Key steps involve repeated PCl5‐induced hydroxylamino N−O bond cleavage leading to insertion of nitrogen atoms, and also piperidine‐induced peroxo O−O bond cleavage leading to insertion of oxygen atoms. The hetero atoms form one pyrrole, two pyran, and one diazepine rings in conjunction with the C60 skeleton...
Makrocyclische Verbindungen haben vielfältige Anwendungen. Die meisten klassischen Makrocyclen sind planare Moleküle. In der Zuschrift auf S. 14810 ff. berichten L. B. Gan et al. über einen N,O‐Heterocyclus mit C60‐Gerüst, den sie in mehreren Stufen durch wiederholte PCl5‐induzierte Spaltung von Hydroxylamino‐N‐O‐Bindungen und Piperidin‐induzierte Spaltung von Peroxo‐O‐O‐Bindungen erhielten. Der fullerenbasierte...
