Beyond acid strength in zeolites: Soft framework counteranions for stabilization of carbocations on zeolites and its implication in organic synthesis

Cabrero-Antonino, Jose R.,Leyva-Prez, Antonio,Corma, Avelino

supporting information, p. 5658 - 5661 (2015/10/12)

The generation of a carbocation with an acid depends not only on the acid strength but also on the ability of the counteranion to stabilize the positive charge left behind. Here we report that despite their relatively weak acidity, zeolites are able to ge
