Abstract
A simple base-promoted intramolecular nucleophilic aromatic substitution of N-[(2-nitrophenyl)sulfonyl]benzamides provides nitriles in very good yields under redox-neutral conditions and avoids the use of toxic cyanide species and transition metals. This process shows broad scope and tolerates various functional groups.
