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 degree C. The pK(b) values of successive N-glucosides have been derived from the Bronsted relation, log k=(pK(b)), using the rate constants of mutarotation, k. The same ralationship served for the determination of basicities of several substituted anilines in methanol at 25 degree 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.
