Zähmung eines blauen Gases—Struktur und Chemie von Hexafluorthioaceton

Angewandte Chemie, EarlyView.
Hexaflouorthioaceton (1), ein blaues Gas bei Raumtemperatur, wurde durch Vakuumpyrolyse des zyklischen Dimers bei 660 °C synthetisiert. Wir diskutieren grundlegende Eigeschaften des schwer greifbaren 1, einschließlich Einkristallstruktur und Kernmagnetische Resonansspektroskopie, obwohl es eine starke Tendenz zur Dimerisierung selbst bei –74 °C zeigt ...
