N-Trimethylsilylimidazole forms bistrimethylsilylimidazolium salts (5) in solution with Me3SiX (X = Br, I, OSO2CF3, or OCIO3). The solutions are conducting, but evidence for ion pairing is presented. Chloro(trimethyl)silane does not produce a salt in solution at ambient temperature but does so at low temperature. N.m.r. evidence is presented for the structures, and used to obtain values of ΔH⊖ and ΔS⊖ for (5; X = Cl).
