Ein chirales, sattelförmiges Nanographen mit zwei Heptagon‐integrierten [4]Helicenen

Angewandte Chemie, EarlyView.
Wir präsentieren eine neuartige Synthesestrategie für ein chirales, sattelförmiges Nanographen (cSNG) über eine zweistufige Oxidation eines prochiralen Anthracen‐Vorläufers. Die Scholl‐Oxidation liefert zunächst ein Schlüsselzwischenprodukt mit sp3‐defekten Heptagonen, die anschließende oxidative Dehydrierung ergibt das vollständig konjugierte cSNG ...

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, EarlyView.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.
