Abstract

Aromatic amines have been synthesized by the simple treatment of carboximides with concentrated azetidine in a fast reaction at room temperature. Strongly negative energies of activation and high reaction order for azetidine were found, which violated Arrhenius theory for a simple activated complex. The application of this reaction to perylenes allowed the synthesis of bathochromically absorbing functional dyes.
