Hossian, Asik; Jana, Ranjan published an article in 2016, the title of the article was Carboxyl radical-assisted 1,5-aryl migration through Smiles rearrangement.Quality Control of 2-Chloro-4-nitrobenzoic acid And the article contains the following content:
We report herein, a silver(I)-catalyzed Smiles rearrangement of 2-aryloxy- or 2-(arylthio)benzoic acids to provide aryl-2-hydroxybenzoate or aryl-2-mercaptobenzoate dimer, resp., through 1,5-aryl migration from oxygen or sulfur to carboxylate oxygen. Mechanistically, the aryl ether moiety undergoes an intramol. ipso attack by the carboxyl radical followed by a C-O or C-S bond cleavage. Aryl-2-mercaptobenzoates undergo oxidative dimerization through a thiol moiety in situ. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).Quality Control of 2-Chloro-4-nitrobenzoic acid
