A conceptually new electrochemical reaction of carboxylic acids was discovered. Under electrolytic conditions, carboxylic acids can be converted to their corresponding anhydrides without decarboxylation and without an additional dehydrating agent. These highly valuable reagents in organic synthesis are obtained in a redox-neutral reaction preserving all carbon atoms while using eco-friendly electrode
发现了一种概念上新的羧酸电化学反应。在电解条件下,羧酸可以转化为它们相应的酸酐,而无需脱羧,也无需额外的脱水剂。这些在有机合成中非常有价值的试剂是在保留所有碳原子的氧化还原中性反应中获得的,同时使用环保电极材料石墨和不锈钢以及酸作为容易获得的起始材料。
