SLJMMARY 1) Acidity constants of 2,3,4,5,6-d5-, 2,4,6-d3-and 3,5-d2-anilinium ion, of 2,6-d2-4-toluidinium and 4-d-2,6-xylidinium ion have been measured in aqueous solution.2) Deuterium substitution of the benzene nucleus decreases the acidity of anilinium ions. A statistical treatment shows that the position of the deuterium atoms has a decisive influence on the acidity constants. The results are consistent with three of the four examined hypotheses of the origin of the measured isotope effects.Technisch-chemisches Laboratorium Eidg.
