Synthesis of non-C2symmetrical NOBIN-type biaryls through a cascadeN-arylation and [3,3]-sigmatropic rearrangement fromO-arylhydroxylamines and diaryliodonium salts

We developed herein a regioselective construction of non- C 2 symmetrical NOBIN-type biaryls through a cascade N -arylation and [3,3]-sigmatropic rearrangement from O -arylhydroxylamines and diaryliodonium salts under mild conditions.
