The nucleophilic substitution upon unactivated monocyclic or polycyclic aromatic or heteroaromatic substrates bearing suitable leaving groups can be achieved by catalyzing the substitution of said leaving groups by an anionic nucleophile with a cyclic or acyclic polydentate chelating ligand. Specific products of this reaction can be used in preparing sulfonylurea herbicides.
