Abstract: 2-Aryl-C.sub.2 to C.sub.5 -alkanoic acids and esters thereof are prepared by heating a 2-(2-oxo-3-cyclohexenyl)-alkanoic acid or ester derivative in the presence of a sulfonic acid or a phosphonic acid at 75.degree. C. to 130.degree. C. while providing a means for removing water from the reaction mixture. In the process new butenolide derivative intermediates have been discovered. Alternatively, the 2-aryl-C.sub.2 to C.sub.6 -alkanoic acids can be prepared from the butenolides by forming a mixture of the 2-(2-oxo-3-cyclohexenyl)-alkanoic acid with acetic anhydride in the presence of an acid scavenging base, allowing the mixture to stand for a time sufficient to form an acetate intermediate, heating the resulting mixture to about 75.degree. C. to about 130.degree. C. to form the betenolide intermediates. Thereafter these intermediates can be heated with sulfonic or phosphonic acid as above while removing water to form the 2-aryl-C.sub.2 to C.sub.
