A new reagent system consisting of NaIO4/KI/NaCl in aq AcOH has been found to be effective in iodinating a variety of activated aromatic substrates via in situ-generated iodine monochloride, to furnish iodoaromatics in excellent yields. This iodination procedure has been applied successfully for a cost-effective synthesis of 3,3′-diaminobenzidine, a key intermediate for preparing proton conducting
已发现由NaIO 4 / KI / NaCl在AcOH水溶液中组成的新试剂系统可有效地通过原位生成的一氯化碘来碘化各种活化的芳香族底物,从而以优异的产率提供碘代芳烃。该碘化方法已成功地用于高成本效益的3,3'-二氨基联苯胺的合成,这是制备燃料电池应用的质子传导膜的关键中间体,具有高收率和99.7%的纯度。
