    • 19 by the condensation of various arylamines and diethyl bromomalonates occurred only when the reaction was performed in vacuum. In the case of diamines, we speculate that under vacuum, the formation of diethyl 2-(2-aminophenylamino)malonate was aided, which was responsible for the higher yield of product than in the open air. Obviously the oxidative aromatization occurs with aerial oxygen on release of vacuum.
