Abstract
Using a facile and cost-effective method, nine bicyclic 1,2,3-triazine 2-oxides were synthesized from o-aminocyanide substrates through an unusual nitration cyclization. The reaction mechanism was studied experimentally and theoretically. Moreover, nine 1,2,3-triazine 3-oxides were also obtained in good yields.
