The preparation of aliphatic aryl tetrafluoro-λ6-sulfanes was achieved by direct addition of readily available chlorotetrafluorosulfanyl arenes to alkenes and alkynes. Systematic substitution of the ligands bound to the tetrafluoro-λ6-sulfanyl group enabled investigations of the substituent effects on the reactivity of aryl tetrafluoro-λ6-sulfanyl-substituted products. The modulation of reactivity was effected by variation of electron-withdrawing or electron-donating effects. All isolable products were fully characterized. In addition structural characterization of these compounds suggested insights into the influence of the substituents on the nature of bonding at the tetrafluoro-λ6-sulfanyl group.

Substituted alkenyl aryl tetrafluoro-λ(6) -sulfanes have been prepared by the direct addition of readily accessible chlorotetrafluorosulfanyl arenes to primary alkynes. Substitution of an apical fluorine of the pentafluorosulfanyl group enables modulation of the reactivity of this little explored functional group while at the same time facilitating the direct investigation of aryl substituent effects on the aryl tetrafluorosulfanyl-substituted products.
