title: Unanticipated formation of ortho-sulfone substituted phenols by anionic thia-Fries rearrangement of (aryl triflate)tricarbonylchromium complexes.
abstract: Tricarbonylchromium complexes of aryl triflates undergo base-mediated anionic thia-Fries rearrangements to generate push-pull substituted [ortho-hydroxyaryl(trifluoromethylsulfonyl)phenol]tricarbonylchromium complexes under very mild reaction conditions.
