Titov V. Physico-chemical basis of electrochemically activated processes of "small" molecules (carbon dioxide, sulfur, freons C1-C2) interaction with organic substrates

The thesis aims for the development of the physicоchemical fundamentals of electrochemical activation of the interaction of various classes of organic substrates (aliphatic and aromatic acylhalides, fluorinated imines, polymers, freons C1-C2 and others) with "small" molecules on path of carboxylation, sulfonilation, dehalogtnation, etc. organic substrates. The possibility of electrochemical activated insertion of carbon carbon dioxide into named substrates was shown for the first time, which opens new nontraditional ways of synthesis ?-oxocarboxylic acids, and fluorinated derivatives of amino acids, fluorinated aliphatic carboxylic acids, copolymers with acrylic fragments etc. in mild conditions. The fundamental regularities of influence of the electronic structure of organic substrates, the nature of the medium and the electrode material on the investigated processes of electrochemical activation carboxylation were elucidated. It is found the ways of improving the efficiency of electrochemical reduction of freons by the use in the reactions studied electron transfer mediators of different classes. It is shown that the electrochemically reduced form of sulfur dioxide can react with freons, acting as a mediator of electron transfer, or also a sulfonylating reagent by entering their molecule as a functional group, to form a fluorine-containing sulfinic acids.
