The reaction of nitrilimines (2) with 1-substituted-l-methylhydrazines (3-6) led to the formation of the respective amidrazones (7) when R=CH3, Ph, and to the acyclic adducts (8,9) when R=CHO and COCH3. The acyclic adducts underwent thermal oxidative cyclization at CH3 to give the unexpected 1,2,4,5-tetrazines (10,11). Dihydro-1,2,4,5-tetrazines (12) were also seperated when R=CHO.
