Electrochemical Decarboxylation/Mumm Rearrangement towards Imides

We report an electrochemically promoted decarboxylation of readily available carboxylic acid and subsequent Mumm rearrangement to synthesize the corresponding imides. The reaction features external oxidant‐free, transition metal‐free mild conditions, and good functional group tolerance, affording various imides in moderate to good yields. Mechanistic studies reveal that the selective oxidation of aliphatic carboxylic acids appears to be the key step in this transformation.
