ABSTRACT
The synthesis of some 1,4-aryldiazines (novel and known dibenzo[a,c]phenazines and quinoxalines) based on the condensation of 1,2-aryldiamines with aromatic 1,2-dicarbonyl compounds in the presence of lithium chloride as a heterogeneous catalyst is presented as convenient and efficient strategy. This method has advantages such as excellent yields, short reaction times, and simple work-up procedure.
