Biochem/physiol Actions

The acute toxicity of aniline involves its activation in vivo to 4-hydroxyaniline and the formation of adducts with hemoglobin. In erythrocytes, this is associated with the release of iron and the accumulation of methemoglobin and the development of hemolytic anemia and inflammation of the spleen. Tumor formation is often observed in the spleen on prolonged administration.

The synthesis and electrochemical oxidative coupling of a highly electron-deficient analogue of aniline results in the formation of soluble electron-deficient oligomers. Oligomers undergo related oxidation and reduction processes that are separated by a wide potential range. The mechanism behind this
