Large-Scale Synthesis of Aniline Trimers in Different Oxidation States

Abstract

Polyanilines are an important class of organic compounds, due to their utility in a large variety of applications. In contrast, oligo­anilines have been employed far more sporadically, in large part reflecting an absence of refined synthetic approaches. Herein, we report, for the first time, a relatively large-scale strategy to generate highly pure aniline trimers at different oxidation states with excellent yields (90–97%).
