Abstract

In this work, aryl diamines were prepared by C–N cross-coupling reactions between aryl halides and ethylenediamine. These reactions were successfully catalyzed by low quantities of Cu2O or CuO (1mol%) employing low reflux temperature and low diamine excess. Products were afforded in good yields (up to 95%).
