Abstract

Abstract: Protonation of fluorotoluenes and fluoromesitylenes in fluorosulfonic acid-antimony pentafluoride solution gives stable methylfluorobenzenonium ions (methylfluorohexadienyl cations). lH and'9F nmr spectra of these ions were obtained and structures assigned. It was found that a fluorine atom takes preference over a methyl group in directing the position of protonation. s an extension of our previous work on fluoro-A benzenonium ionsa we have ...
