Abstract
The rearrangement of p‐tolyl acetate in nitrobenzene solution catalysed by aluminium chloride gives the o‐hydroxyketone only as rearrangement product. o‐Tolyl acetate under the same treatment yields mainly the para‐substituted hydroxyketone together with a small amount only of the ortho‐substituted compound. Both of these rearrangements appear to be intramolecular and the interpretation proposed for the titanium tetrachloride catalysed transformations of these esters may also be applied in the present case.
