Despite the widespread application of hypervalent iodines, the corresponding λ3-bromanes are less explored. Herein the authors report a general, safe, and high-yielding strategy to access cyclic diaryl λ3-bromanes. These unique compounds feature reactivity that is appealing and complementary to that of λ3-iodanes, generating arynes under mild reaction conditions and in the presence of a weak base. Accordingly, formal meta-selective transition-metal-free C-O and C-N couplings may be achieved. Mechanistic studies unambiguously support the aryne generation mechanism.
