POLAROGRAPHIC AND POTENTIOSTATIC REDUCTION OF CARBODIIMIDES: A MECHANISTIC STUDY
The polarographic reduction of aromatic carbodiimides in anhydrous aprotic solvents goes through a carbene intermediate by a diffusion controlled process in two one-electron steps. The first step is the rate-determining step and converts the carbodiirnide to a radical anion (6) that reduces further by a fast one-electron step to a carbene dianion intermediate (7). This abstracts an oxygen, ...
متن کاملPolarographic Reduction of Benzoate in Acet,pnitrile
The polarographic wave observed for acetonitrile solutions of benzoic acid is due to reduction of the acid proton: the apparent diffusion current constant for the wave increases with concentration of benzoic acid as expected for the reduction of the acidic proton of a slightly dissociated acid. No wave was observed for ethyl benzoate. The situation in respect to the electrochemical reduction of...
متن کاملVoltammetric and Polarographic Studies of Eriochrome Black T - Nickel(II) Complex
EBT is a carcinogenic azo-compound. It is well known that EBT has chelating properties. Therefore, EBT has been widely used for the determination of calcium, magnesium, manganese, zinc, zirconium, nickel, copper, thulium and cobalt1−5. Literature surveys have shown that extensive polarographic, spectroscopic and colorimetric studies on some metal complexes with EBT have been carried out4−13. Th...

متن کاملPolarographic reduction of adenine and cytosine residues in denatured DNA.
Polarographie reduction of adenine and cytosine moieties in denatured DNA was followed by means of differential (derivative) pulse polarography. The measurements of the reduction currents yielded by samples of denatured DNA differing in guanine+cytosine (G + C) content showed that both cytosine and adenine residues were reduced in DNA in the pH range of 6.0 —8.7. The con tribution of their red...
