The condensation of isomeric cresols with γ-butyrolactone and β-chlorobutyric acid in the presence of an excess of aluminum chloride leads to mixtures of isomeric β-cresylbutyric acids.The use of tetrachloroethylene as solvent in these reactions affects not only the yield but also the isomeric composition of the reaction products.
