Selective Ortho-Hydroxylation–Defluorination of 2-Fluorophenolates with a Bis(m-oxo)dicopper(III) Species

The bis(mu-oxo) dicopper(III) species [Cu-III 2(mu-O)(2)(m-XYLMeAN)](2+) (1) promotes the electrophilic ortho-hydroxylation-defluorination of 2-fluorophenolates to give the corresponding catechols, a reaction that is not accomplishable with a (eta(2) : eta(2)-O-2) dicopper(II) complex. Isotopic labeling studies show that the incoming oxygen atom originates from the bis(mu-oxo) unit. Ortho-hydroxylation-defluorination occurs selectively in intramolecular competition with other ortho-substituents such as chlorine or bromine
