Electrochemistry of Organophosphorus Compounds

Progress in electrochemistry of organophosphorus compounds is rewieved. Mechanisms of oxidation and reduction reactions under the conditions of homogenous electrocatalysis and possibility of use the primary compounds for the synthesis of various organic and organoelement compounds are considered.

Electrochemical amination of unsaturated and aromatic compounds

The mechanism and synthetic perspectives of an indirect cathodic amination of unsaturated and aromatic substrates are considered. The influence of experimental conditions on the state and reactivity of the aminating reagent in solution is studied. The key role of the electrolyte acidity and redox properties of the reagents and intermediates in the obtained isomeric composition and the yield of the amination products is demonstrated.

Electrochemical reduction of cobalt and nickel complexes with ligands stabilizing metal in low oxidation state

Electrochemical reduction of cobalt(ii) complexes containing π-acceptor ligands (L = bpy, Ph2Ppy) proceeds through three consecutive reversible steps: one-electron transfer to form a more stable CoIL complex, transfer of two electrons at more negative potentials to form an anionic [NiL]– complex, and reduction of the ligand to the radical anion. The stability of the cobalt complexes with different ligands decreases in the series Ph2Ppy > Ph3P > bpy.

Anodic synthesis and molecular structure of dodecaethylhexaamidobisphosphonium diperchlorate

AbstractThe electrochemical oxidation of hexaethyl triamidophosphite in the absence of nucleophiles specially introduced into the electrolyte was studied by anodic voltamperometry and preparative electrolysis. The reversible one-electron oxidation of the triamidophosphite molecule gives an unstable radical-cation, which reacts with a molecule of the starting compound to give a dimeric radical-cation, whose subsequent oxidation leads to dodecaethylhexaamidobisphosphonium diperchlorate. This product is the first example of an acyclic, doubly charged bisphosphonium cation with a

. The crystal structure of this compound was obtained by x-ray diffraction structure analysis.

Electrochemical reduction of the complex of Zn(II) with 4-(2′-oxopropylidene)-2,2,5,5-tetramethyl-3-imidazolidine-1-oxyl

The thermal transformations of nitrocellulose are accompanied by the formation of RN02− radicals and allyl radicals. A mechanism for the formation of these radicals was proposed.

ELECTROCHEMICAL REACTIONS OF CO(II), CU(II), AND ZN(II) COMPLEXES WITH 4-(2'-OXOPROPYLIDENE)-2,2,5,5-TETRAMETHYL-3-IMIDAZOLIDINE-1-OXYL

Abstract Some application features of the competitive reactions method (C.R.M.) for anodically generated agents have been considered. Quantitative characteristics of the (RO) 3 P, (RO) 2 POSiMe 3 , (EtO) 2 PONa, and I 2 electrochemically induced intermediates have been presented. It is discussed how to apply the obtained information for stating the nature of respective species.
