Abstract Several ketone N-phenylsemicarbazones were electrooxidized in the presence of potassium iodide and a base using methanol as the solvent to give nearly commensurate amounts of methyl N-phenylcarbamate and the corresponding dimethyl acetals. Continuous evolution of gaseous nitrogen was observed from the anolyte during the electrooxidation. The reactions were carried out under very mild reaction
摘要 在碘化钾和碱的存在下,以甲醇为溶剂,对几种酮 N-苯基氨基甲酸酯进行电氧化,得到几乎等量的 N-苯基氨基甲酸甲酯和相应的二甲基缩醛。在电氧化过程中观察到从阳极电解液中持续释放出气态氮。这些反应是在非常温和的反应条件下进行的,据推测是通过四电子氧化过程进行的,其中碘离子作为电子载体起着重要的作用。图形概要
