Direct evidence is reported for the existence of unsubstituted ethylenebenzenium ions in the gas phase, based on sup 13}C-labeling of a methylene position in the precursor beta}-phenylethyl alcohol or chloride. The sup 13}C location in the products of the substitutionreaction induced by gaseous cations in the presence of methanol is consistent with the occurrence of ethylenebenzenium ions3 which
