摘要：

Ambient temperature melts were derived from trimethylsulfonium bromide (TMSuBr) and AlBr3, AlCl3, or HBr. The aluminum halide melts have low-wavelength UV cutoffs and single-band H-1 NMR spectra. In the TMSuBr-HBr system, the formation of HBr2- and likely existence of H2Br3- are indicated by H-1 NMR and IR spectra. Conductivity and viscosity data indicate stronger TMSu(+)-anion interactions than those between substituted imidazolium and halide anions. A Grotthus mechanism may operate for conduction in TMSuBr:HBr melts.
