Abstract: The reactions of dimethoxynaphthelenes with ClSO3SiMe3 were studied in CH2Cl2at room temperature and examined hy 1H NMR spectroscopy. The influences of the kind andamount of sulfonating agents on the reaction have been examined. The kinetics of formationof 2,4-disubstituted sulfonates has been studied. An anhydride was proved to be formed dur-ing reaction

Key words: methoxynaphthelene, sulfonation, kinetics
