with a nucleophile (AlkO−, ArO−, AcO−, Hal−, CN−, NCO−, ArNH2, AlkNH2, Alk2NH), at room temperature, results in elimination of an N2 molecule to afford ortho-substituted azobenzenes. This reaction could be suitable for mild phenylation of carboxylic acids and other compounds containing active hydrogen. A plausible reaction pathway for the reaction is discussed.
