A Ni-catalyzed aryl C–Nbondcleavage of mono-protected anilines, N-arylsulfonamides, has been developed. A new N-heterocyclic carbene derived from benzoimidazole shows high reactivity for the C–Ncleavage/C–C cross-coupling reaction. The ortho-directing group is not required to break the C–Nbond of sulfonyl-protected anilines, which are not limited to π-extended anilines. The mechanistic studies
