Abstract

Abstract : Novel members of the league of extraordinary superacids, namely the Brønsted superacid H[Al(OTeF5 )4 ] and the Lewis superacid "Al(OTeF5 )3 ", have been synthesized starting from AlEt3 and HOTeF5 . In their Communication onpage 8263 ff., S. Riedel and co‐workers describe the preparation and crystallization of five salts of the weakly coordinating anion [Al(OTeF5 )4 ] −, which is shown in the spotlight, through the use of H[Al(OTeF5 )4 ].
