Abstract

Starkes Fluor: In Einklang mit theoretischen Studien zu α-Fluorcarbanionen ergab eine Röntgenstrukturanalyse für das α-Fluorbis(phenylsulfonyl)methid-Anion eine pyramidale Konfiguration (siehe Bild). Anspruchsvolle Rechnungen und NMR-spektroskopische Studien zeigten, dass elektronenziehende Substituenten die Eigenschaften von Bis(phenylsulfonyl)methid-Anionen entscheidend beeinflussen.
