Paired off: The title reaction leads to a series of o-pyridinium phenols (1) and anilines (2). The experimental and computational studies indicate that the key step involves homolytic cleavage to give a radical pair, which undergoes solvent-cage recombination to give the product. Copyright

The vicinal disubstitution reactions of diaryliodonium salts with pyridine N-sulfonamidates to give o-pyridinium anilines were fully examined. A reaction pathway of N-arylation occurring at the amidate group followed by a radical rearrangement is proposed. The electronic effects of various substituents in this radical rearrangement were investigated.
