Basicities of p-toluidine, m-toluidine, p-chloroaniline, m-chloroaniline and m-nitroaniline N-glucopyranosylamines have been determined by potentiometric titration in methanol at 25°C. The pKb values of successive N-glucosides have been derived from the Brönsted relation, log k = f (pKb), using the rate constants of mutarotation, k. The same relationship served for the determination of basicities of several substituted anilines in methanol at 25°C. Basicity constants of the aniline derivatives and of the N-arylglucopyranosylamines in methanol have also been correlated with analogous constants of the compounds in water.
