Noteworthy, the reaction went to completion in the case of electron rich aniline 1n, the remaining mass being in the form of bisaniline DCP (28 %) and bis-morpholine DCP (16 %), whereas in 1m the reaction was not complete, and the main product was the bismorpholine DCP (35 %), with no formation of the bis-aniline DCP. This suggests a high dependency on the electronics of the arylamines.
