Tetrazine



    Tetrazine is an unstable isomers exist: 1,2,3,4-tetrazines, 1,2,3,5-tetrazines and 1,2,4,5-tetrazines

1,2,3,4-tetrazines

1,2,3,4-Tetrazines are often isolated fused to an aromatic ring system and are stablized as the dioxide derivatives.

1,2,4,5-tetrazine

1,2,4,5-Tetrazines are very well known and myriad 3,6-disubstituted 1,2,4,5-tetrazines are known [1]. These materials are of use in the area of energetic chemistry.

The compound 3,6-di-2-pyridyl-1,2,4,5-tetrazine [2] has two acetylene unit:


With norbornadiene fused to an arene the reaction stops at an intermediary stage [3]
