The prototypical anionic phospho-Fries rearrangement involves the conversion of an aryl phosphate ester [ArOP(=O)(OR)2] to an ortho-hydroxyarylphosphonate [o-OH-Ar-P(=O)(OR)2].

The Fries rearrangement of model aryl formate esters, promoted by boron trichloride, has been investigated by means of NMR spectroscopy (both experimental and computational) and by DFT calculations. with this reaction. Fries rearrangement has been employed in the key steps in the total synthesis of muricadienin, the unsaturated putative precursor in the biosynthesis of, The anionic phospho-Fries rearrangement of chiral ferrocenyl phosphates yields diastereomeric enriched 1,2-, Liquid-phase Fries rearrangement of aryl esters catalyzed by heteropoly acid H. Anionic phospho-Fries rearrangement has been successfully applied to investigate ferrocene chemistry.
