The polarographic reduction of some arylidene derivatives of benzoic hydrazide are investigated at the DME. The polarograms in solutions of pH≤8 consist of a single wave corresponding to 4 electrons in acid media and 2 electrons in alkaline ones. The wave splite into two daughter waves in media of pH≥10, the more negative wave increases in height at the expense of ihe original one with rise of pH. The reduction waves are essentially diffusion controlled with one proton and two electrons in the rate determining step. The electrode reaction is discussed and the important kinetic parameters are determined. 相似文献

1 INTRODUCTION 4-Acyl pyrazolones and their derivatives, reported to behave as effective chelating and extracting rea- gents for many metal ions, not only play a key role in coordination compounds with wide applications in several fields, from new materials[1] to catalysts[2] as precursors for CVD in the microe-lectronic Indus- try[3] and as potential antitumourals[4], but also are the focus of research as potential antifungal agro- chemicals and widely used as antiviral, antipyretic anal… 相似文献

Addition of substituted benzyl bromides to dialkyl azodicarboxylates under aqueous zinc-mediated addition conditions occurs readily to afford monobenzylated hydrazides in good to excellent yields. The reaction is tolerant of a variety of substituents on the benzyl bromide ring. Several dialkyl azodicarboxylates were successfully tested under the reaction conditions. The limitations of the reaction are also addressed.
