by using 2-amino alkylbenzimidazole (MBIP amine) as a new and removable N,N-bidentate directing group. This strategy gives a variety of functionalized thioethers in moderate to excellent yields in a simple and efficient way. Importantly, the substrate scope is not limited to aromaticamides; diverse alkenyl amides are also compatible. Furthermore, this synthetic approach provides a potentially feasible
