Expanded Cubane: Synthesis of a Cage Compound with a C56 Core by Acetylenic Scaffolding and Gas-Phase Transformations into Fullerenes

Formal insertion of buta‐1,3‐diynediyl moieties into all twelve CC single bonds of octamethoxycubane gives the explosive expanded cubane 1. Fourier‐transform ion‐cyclotron‐resonance (FT‐ICR) mass spectrometric studies show that 1 readily loses its eight MeO groups and subsequently rearranges into f...

Zusammenfassung:Formal insertion of buta‐1,3‐diynediyl moieties into all twelve CC single bonds of octamethoxycubane gives the explosive expanded cubane 1. Fourier‐transform ion‐cyclotron‐resonance (FT‐ICR) mass spectrometric studies show that 1 readily loses its eight MeO groups and subsequently rearranges into fullerene ions. In the positive ion mode, these ions undergo fullerene coalescence reactions.
