The literature data and results of author's investigations concerning the processes of electrochemical conversion of carbon, sulfur anal nitrogen oxides, as well as freons into valuable organic products are briefly presented Considerable attention is devoted to the possible mechanisms of these processes, the role of ion-radicals and free radicals, the influence of reagent structure, the conditions of electrolysis and other factors on the composition and yield of the formed products, the problems of development of this perspective field which is on the boundary of physical chemistry, organic chemistry and ecology.
The influence of oxidation ability of stable cation radicals of parasubstituted triphenylamines: (X-C6H4)3N+.A-, where X = -OCH3, A- = SbCl6- (I); X = -CH3, A- = SbCl6- (II); X = -Br, A- = SbCl6- (III); X = -OCH3, A- =BF4- (IV)) on the pyrrole polymerization process and the physico-chemical attributes of the resulting polymer were studied. In the case of I, II and IV cation radicals the formation of polypyrrole soluble in CH3CN was found to take place. It was revealed that with rising oxidation ability of cation radicals in the I < II < III trend, the rate of their reaction with pyrrole increases as a result the conductivity of the polypyrrole enhances, the number of paramagnetic centres alters, the yield of the soluble polymer reduces.
