The substitution and direct departure of the ipso ‐H by OH radicals has long been considered as the main route for the hydroxylation of aromatic compounds in water. Detailed isotope‐labelled experiments showed that part of the ipso ‐H shifted to the adjacent carbon in the aromatic ring and was retained in the final phenols (1,2‐NIH shift). The results indicated that besides the common ipso ‐substitution, a Wagner–Meerwein rearrangement of the carbocation intermediates also exists during the hydroxylation of aromatic compounds in H 2 O via advanced oxidation technologies.
