摘要：

The reaction of arylazides with 1,2‐diaminoethylenes (1a‐b) or α,β‐diaminostyrenes (1c‐f) gave N‐(1,2‐diaminoethylideneanilines (2a‐e) and N‐(1,2‐diamino‐2‐phenylethylidene)anilines (2g‐i), respectively. These amidine derivatives are formed through the rearrangement of unstable 1‐aryl‐4,5‐diamino‐v‐triazolines. The regiospecificity of the cycloaddition reaction has been elucidated on the basis of the products obtained. Copyright © 1979 Journal of Heterocyclic Chemistry
