PROCESS FOR THE NUCLEOPHILIC SUBSTITUTION OF UNACTIVATED AROMATIC AND HETEROAROMATIC SUBSTRATES

摘要

Abstract of the DisclosureThe nucleophilic substitution upon unactivatedmonocyclic or polycyclic aromatic or heteroaromaticsubstrates bearing suitable leaving groups can beachieved by catalyzing the substitution of saidleaving groups by an anionic nucleophile with a cyclicor acyclic polydentate chelating ligand. Specificproducts of this reaction can be used in preparingsulfonylurea herbicides.
