The Fries rearrangement of phenyl acetate is catalysed by acidic zeolites such as H-Nu-2 and H-ZSM-5, with selectivities of 2-6:l in favout of para-substituted products. The Fries rearrangement of phenyl esters affords a mixture of o-and phydroxyphenylketones, together with phenol as a hydrolysis p
