UNUSUAL TRANSFORMATIONS OF ARYLHYDRAZONOYL CHLORIDES OF ETHYL OXALATE

X-ray diffraction structural analysis, IR, 13C 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.
