FIELD: organic chemistry and synthesis, chemical technology.
SUBSTANCE: invention relates to a method for synthesis of benzidine derivatives. Invention proposes a single-step method for synthesis of derivatives of benzidine. Method involves oxidation of corresponding aromatic amines with hydrogen peroxide in organic solvent medium in the presence of catalytic amounts of substituted iron or cobalt phthalocyanines. The proposed method provides preparing different derivatives of benzidine with good yield and high content of the main substance. Method can be used for the development in aims of industrial technology. Derivatives of benzidine are used widely as redox-indicators for determination of some metal ions, in immunoenzyme analysis and for preparing electroluminescent materials also.
EFFECT: improved preparing method.
