A super method! The synthesis of the donor-free Lewis superacids Al(ORF)3 with ORF=OC(CF3)3 (1) and OC(C5F10)C6F5 (2), as well as stabilization of 1 with the very weak Lewis bases PhF, 1,2-F2C6H4, and SO2, is reported (see figure). Applications of 1 and 2 in bond heterolysis reactions with Cl[BOND]CPh3 giving the trityl cation and the respective weakly coordinating anion [ClAl(ORF)3] are also described.
