compounds including azo, azosulfone, and arylazides were prepared in good yields with good purity. Cathodically generated aryldiazoniums and anodically produced copper(Ι) ions were used to perform Sandmeyer reactions. To improve the method, an H-type self-driving cell equipped with a Zn rod as an anode was introduced and used for two-phase aryldiazonium production.
首次报道了在两相系统(乙酸乙酯/水)中由硝基芳烃电化学生成芳基重氮盐。以良好的收率和良好的纯度制备了包括偶氮,偶氮砜和芳基叠氮化物在内的一些化合物。阴极产生的芳基重氮和阳极产生的铜(I)离子用于进行Sandmeyer反应。为了改进该方法,引入了以Zn棒为阳极的H型自驱动电池,并将其用于两相芳基重氮的生产。
