摘要：An unusual substitution reaction of an aromatic sulfonic group based on 3-carbonyl-4-phenolsulfonic acid was discovered in a diazo-coupling process. The reaction occurred under mild reaction conditions (pH 8.0-9.0, 0-5 degrees C, solvent: water) within a short reaction time (1 h). A plausible substitution reaction mechanism by phenol-ketone resonance was proposed. (C) 2013 Bing-Tao Tang. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
