Polarographic behaviour of α- and γ-substituted acetoacetanilide derivatives in alcoholic aqueous media

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 ofpHis 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-diN-(3′-pyridyl)amide-1,4-dihydro-pyrazine as an electrolysis pr
