• The Henkel reaction of dipotassium 1,8-naphthalenedicarboxylate in naphthalene as a dispersion medium gave dipotassium 2,6-naphthalenedicarboxylate (<B>1</B>) in a higher yield and with a better reproducibility than the reaction without a dispersion medium. Catalysts, particularly zinc catalysts, were examined in detail. The anion moiety of zinc catalysts affected the reaction, and the halide anion was effective for the selective formation of <B>1</B>. The addition of potassium halide to the zinc catalysts also increased the yield of <B>1</B>. The catalytic activity of the halide anion increased in the order; Cl<SUP>−</SUP><Br<SUP>−</SUP><I<SUP>−</SUP>. The activity of the zinc catalysts was also compared with that of cadmium catalysts.
