Abstract

Label-enabled: Studies with 2H-, 18O-, and 34S-labeled aryl triflates show that lithium diisopropylamide-mediated thia-Fries rearrangement proceeds through an irreversible ortho deprotonation (see scheme; DIPA=diisopropylamine, LDA=lithium diisopropylamide). In contrast, ortho metalation results exclusively in the generation of a benzyne.
