摘要: An electrochemical treatment of differently protected aniline or napthylamine results in the preparation of unsymmetrical 2, 2′-diaminebiaryls provided with different protecting groups. The treatment involves the protecting groups prior to the C, C coupling step. The co-reactants generally have different oxidation potentials which results from the selection of the protecting groups. The treatment also enables controlled access to the individual amino functions of the 2, 2′-diaminobiaryls by subsequent selective deprotection.
