A base-mediated aerobic oxidation of alkylbenzimidazoles for the preparation of carboxylic acids is described. A number of aliphatic carboxylic acids have been prepared in good to excellent yields via a C–Cbond rupture process. Preliminary mechanistic studies suggest the reaction undergoes a radical pathway initiated by strong bases such as potassium amide. This type of transformation provides an
