Green syntheses of two different series of new benzofuran derivatives were carried out by anodic oxidation of 4,4′-biphenol (4BP) in the presence of some CH-acid compounds (malononitrile, methyl cyanoacetate and ethyl cyanoacetate) as nucleophiles by controlling the potential during electrolysis.

Low Concentration

The anodic oxidation of sodium acetate in the presence of a series of 1,2-disubstituted ethylenes was performed in acetonitrile–water solution. Under low concentration of substrates, very good yields of the monomeric 1,2-dimethylated products were obtained. In the case of diethyl fumarate, an increase in concentration caused a decrease in the ratio of monomer to polymer when all other parameters were held constant.The stereoisomers of the products were separated and their physical properties are reported.

The electrochemical synthesis of polyaniline (PANI) on mild steel, aluminum and copper from the sodium benzoate solutions has been investigated. It has been shown that thin, highly adherent, polyaniline films on the investigated metals could be obtained by anodic oxidation with current densities in the range of 0.5 and 1.5 mA cm-2. The corrosion behavior of mild steel, aluminum and copper with polyaniline coating in 0.5 mol dm3 NaCl (pH 3) solutions, has been investigated by polarization technique. The corrosion current densities, porosity and protection efficiency was determined. It has been shown that polyaniline coating provided corrosion protection of all mentioned metals.
