Abstract

Over a time period of about 30 years, the anionic Fries rearrangement has been developed as a common synthetic concept in aromatic chemistry.(1, 2) This rearrangement offers a mild and regioselective complement to a nonselective acid-catalyzed Fries rearrangement(3) and photo-Fries rearrangement.(4) Since the primary work of Lloyd-Jones,(5a) the anionic thia-Fries rearrangement, mainly involving a 1,3-sulfonyl migration reaction of aryl ...
