A novel electrochemical oxidative decarboxylation of disubstituted malonic acids leading to dimethoxy ketals is described. In the presence of NH3, a wide range of disubstituted malonic acids was transformed into the corresponding ketals in good to excellent yields under electrochemical conditions. When the crude reaction mixture, obtained after electrolysis, was directly treated with 1 M aq HCl, the
描述了导致二甲氧基缩酮的二取代的丙二酸的新型电化学氧化脱羧。在NH 3的存在下,在电化学条件下,大量的二取代的丙二酸以良好或优异的产率转化为相应的缩酮。当将电解后获得的粗制反应混合物直接用1 M HCl水溶液处理时,最初生成的缩酮可以在单容器操作中顺利转化为相应的酮。
