X-ray diffraction structural analysis, IR, C-13 NMR, and PMR spectroscopy was used to establish that the products of the reactions of arylhydrazonoyl chlorides of ethyl oxalate and sodium ethylate are 1,4-diaryl-3,6-dicarboethoxy-1,4-dihydro-1,2,4,5-tetrazines and 1-aryl-3-carboethoxy-4-arylhydrazono-5-pyrazolones.
