Abstract

The electrochemical properties of the N-substituted α-diphenylphosphinoglycines N-(2-methoxybenzyl) diphenylphosphinoglycine (1), N-(pyrazin-2-yl) diphenylphosphinoglycine (2), N-(1-adamantyl) diphenylphosphinoglycine (3), and N-(2,5-dimethoxycarbonylphenyl) diphenylphosphinoglycine (4) obtained in the three-component condensation of diphenylphosphine, glyoxylic acid hydrate, and the corresponding amine were studied by cyclic voltammetry on a glassy carbon electrode. The structure of compound 4 was confirmed by X-ray diffraction analysis. Compounds 1–4 exhibited electrochemical activity in the anodic region of potentials due to the presence of an oxidizable diphenylphosphine fragment in the molecule. Compound 4 can also be electrochemically reduced at the cathodic potentials of the working electrode due to the ester groups in the aromatic fragment.
