1,2,3,4-Tetrazine derivative is a kind of nitrogen-rich compounds, which exhibits higher energetic density and potential application on the field of energy materials. In this paper, through the [4+2] cycloaddition of α-halo-N-acylhydrazones to diazodicarboxylates, various 1,2,3,4-tetrazine derivatives could be afforded in good to excellent yields in mild reaction conditions. The 1,2-diaza-1,3-dienes were generated in situ with the help of base, subsequently, in the absence of catalyst, the [4+2] cycloaddition proceeded well. Besides, this reaction can be performed on the gram scale and has good substrate scope.

Key words: 1,2,3,4-tetrazine, [4+2] cycloaddition, diazodicarboxylates, α-halo-N-acylhydrazones
