An Amorphous Teflate Doped Aluminium Chlorofluoride: A Solid Lewis‐Superacid for the Dehydrofluorination of Fluoroalkanes

Bui, Minh; Hoffmann, Kurt F.; Braun, Thomas; Riedel, Sebastian; Heinekamp, Christian; Scheurell, Kerstin; Scholz, Gudrun; Stawski, Tomasz; Emmerling, Franziska

An anion-doped aluminium chlorofluoride AlCl0.1F2.8(OTeF5)0.1 (ACF-teflate) was synthesized. The material contains pentafluoroorthotellurate (teflate) groups, which mimic fluoride ions electronically, but are sterically ...
