Abstract

The basic and acidic characteristics of N,N'-diaryl- and N,N'-dimethyl-substituted 3-amino-1-imino-1H-isoindoles, which are determined by electronic factors related to the nature of the substituents at the exocyclic nitrogen atoms, were studied. Electron-donating alkyl groups lead to an increase in the basicity of these compounds. The introduction of aryl groups containing electron-withdrawing substituents (NO2, COMe) at the p-positions leads to significant weakening of the basic characteristics and strengthening of the acidic characteristics. The protonation and deprotonation and also methylation processes in the series of compounds were studied.
