Triarylsulfonium halides have been prepared by the reaction of diaryl sulfoxides with aromatic hydrocarbons in the presence of a large excess of aluminum halide. The structures of the salts were established by pyrolysis and subsequent glpc analysis of the pyrolysates. On the basis of product ratios produced in the pyrolysis reactions, it was possible to suggest what seemed to be the most plausible mechanism of thermal decomposition of the salts. ...
