摘要

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 membranes for fuel cell applications, with ...
