A theoretical analysis has been carried out of the competing cyclization reactions of 1,2,4-triazahexa-1,3,5-triene and 1,2,4-oxadiazahexa-1,3,5-triene systems using as example C-(arylazo)imines and C-nitrosoimines containing aromatic or aliphatic substituents on the amine nitrogen atom, and also their benzoannelated derivatives.How to Cite
