A facile synthesis and isolation of pristine silicon tetrakis(trifluoromethanesulfonate), Si(OTf)<sub>4</sub> , is reported, acting as the first neutral silicon-based Lewis superacid suitable towards soft and hard Lewis bases. Its OTf groups have a dual function: they are excellent leaving groups and modulate the degree of reactivity towards soft and hard Lewis bases. Exposed to soft Lewis donors, Si(OTf)<sub>4</sub> leads to [L<sub>2</sub> Si(OTf)<sub>4</sub> ] complexes (L=isocyanide, thioethe ...[more]
