TRANSPOSITION DES PHENYLACETATES D'ARYLE SELON FRIES

Abstract
The Fries transposition of phenyl, p‐tolyl and o‐tolyl phenylacetates was studied. The properties of the ortho‐ and para‐hydroxyketones obtained in this transposition were examined. Particularly, the reaction of ethyl formate or acetic anhydride on the o‐hydroxydesoxybenzoin leads to the corresponding isoflavones.
