18 - 102Selective Oxidation of Substituted Xylenes to Toluic Acids byHypochlorite–Ru System under Phase - Transfer Conditions. —Under phase-transfer conditions the reactant is transferred to the aqueous phaseas the sodium salt of the benzoic acid immediately after the oxidation of themethyl group. Thus, only one of the two methyl groups is oxidized. Unsubsti-tuted xylene or xylenes bearing electron-donating groups form ring-chlorinatedproducts together with some side chain chlorinated products. — (SASSON,Y.; AL QUNTAR, A. E.-A.; ZORAN, A.; Chem.
