Abstract
The improved preparation of the Lewis superacid Al(OTeF5)3 and several solvent adducts is presented. These range from thermally stable adducts to highly reactive, weakly bound species. DFT calculations on the ligand affinity of this Lewis acids were performed in order to rank their remaining Lewis acidity. An experimental proof of the Lewis acidity is provided by the reaction of Al(OTeF5)3 with [PPh4][SbF6] and OPPh3. Furthermore, reactivities towards chloride salts as well as CH3SiCl and CH3SiF are shown.
