Abstract: The first observation (nmr) of arylonium ion formation via aryl participation in strong acid solution was achieved. The p-anisonium, 2, 4, 6-trimethylphenonium, and pentamethylphenonium ions were obtained in SbFs-SO2 solution at low temperature upon ionization of the corresponding P-phenylethyl chlorides. Conditions permitting bridged phenonium (arylonium) ion formation over competing classical benzylic ion (styryl cation) ...
