CuH-catalyzed intramolecular cyclization and intermolecular allylation of benzimidazoles with allenes have been described. The reaction proceeded smoothly with the catalytic system of Cu(OAc)2/Xantphos and catalytic amount of (MeO)2MeSiH. This protocol features mild reaction conditions and a good tolerance of substrates bearing electron-withdrawing, electron-donating, or electron-neutral groups. A

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
