Reactions of Benzotriazolo[2,1-a]benzotriazole Derivatives. 2. An Unusual Hydrolysis-Oxidation Reaction

摘要

In summary, we have found that further nitration of 3 leads to the formation of moisture sensitive nitration products which undergo further oxidation to give o-quinone-like species 4 and 7. However, the tetraaza-pentalene subunit remained unaffected further demonstrating the robust nature of this heterocyclic system.
