Article abstract of DOI:10.1007/BF00476989

Diethylamine (DEA) and triethylamine (TEA) can function as sources for the two-carbon component in the reverse azadiene synthesis.Reaction of 5,7-dimethylpyrimido<4,5-e>-1,2,4-triazene-6,8-dione, 6,8-dimethylpyrimido-<5,4-e>-1,2,4-triazine-5,7-dione, or 1
