Hindawi, Jalal A. Zahra, Mustafa M. El-Abadelah, Bassam A. Abu Thaher, Klaus-Peter Zeller] Summary.: Direct interaction between model anilines and an 1,3-dipolar nitrile imine, derived from 2-[N′-(1-chloro-2-oxopropylidine)hydrazine]benzoic acid, yielded the respective acyclic amidrazones. The latter adducts underwent CDI-induced cyclocondensation involving the hydrazone-NH terminus and the activated carboxy group to produce the corresponding dihydro-1,2,4-benzotriazepin-5-ones.
