N1, N4,3,6-Tetramethyl- N1, N4-diphenyl-1,4-dihydro-1,2,4,5-tetrazine-1,4-dicarboxamide was prepared from 3,6-dimethyl-1,6-dihydro-1,2,4,5-tetrazine, bis(trichloromethyl) carbonate and N-methylaniline. Its structure was confirmed by single-crystal X-ray diffraction. This reaction yields the title compound rather than N1, N2,3,6-tetramethyl- N1, N2-diphenyl-1,2-dihydro-1,2,4,5-tetrazine-1,2- dicarboxamide. The central tetrazine ring of the title compound exhibits a boat conformation and is therefore not homoaromatic.
