  • Patent number: 4135051
    Abstract: 2-Aryl-C.sub.3 to C.sub.6 -alkanoate esters are prepared economically by reacting an enol ether of an aryl alkyl ketone with a trivalent thallium salt in an organic solvent. The trivalent thallium ions can be regenerated by adding a peracid and a reactive form of manganese, ruthenium, cobalt, iridium, hafnium, osmium or neobium to oxidize monovalent thallium ions to the trivalent state, in a sequential, continuous or stoichiometric procedure. The ester intermediate product is then converted to the corresponding 2-aryl-C.sub.3 - to C.sub.6 -alkanoic acid or salt thereof. The aryl group is selected so the resulting acid product will be a useful compound such as anti-inflammatory, analgesic and anti-pyretic drug or agriculturally useful product. Examples of drug acids which can be made by this process include ibuprofen, flurbiprofen, fenoprofen and naproxen and the like.
