|Abstract:||Some oxygen-bonded substituents were investigated as leaving groups in photoinduced ArSN1 reactions. Irradiation of aryl imidazylates and of the corresponding imidazolium salts mainly caused homolysis of the ArO?S bond. However, previously unexplored tri?uoroethoxy aryl sulfates were found to undergo e?cient metal-free arylation. The sulfates were conveniently generated in situ by dissolving the corresponding imidazolium salts in basic 2,2,2-tri?uoroethanol.|
