Summary

Silyl triflates containing organosilicon cations stabilized by the 2,6–bis(methoxymethyl)phenyl or by the 2,6–bis(methylthiomethyl)phenyl ligand have been prepared starting from the corresponding chlorosilanes. Ionic structures are found in solution as well as in the solid state. The cations all show a trigonal bipyramidal geometry at silicon in the solid state. Oxygen- and sulfur-stabilized organosilyl cations differ remarkably in their reactivity towards nucleophiles.
