摘要:
A polarographic study on a series of newly synthesized compounds, namely N-(3'-pyridyl)-2,3-dioxobutanamide-2-arylhydrazones (1 a-f) in a wide range of pH is reported and discussed. CPE indicated that these compounds are reduced in the hydrazono form. A scheme is proposed and confirmed through isolation and identification of 2,5-dimethyl-3,6-di[N-(3'-pyridyl)amide]-1,4-dihydro-pyrazine as an electrolysis product.
