New processes of the electrochemically-induced activation of polyfluoroalkylhalides are studied and the possibility of electrochemically activated insertion of carbon dioxide molecules into geminal freons (CF3CCl3, CF2Cl2, CF3CClBr2, CF3CFBr2) to form a hard-carboxylic acids in high yields is shown. In order to reduce the energy expenses for carrying out of electrochemical carboxylation of CFCs, the possibility of its implementation in the power saving homogeneous catalytic mode using electron transfer mediators is found. The influence of various factors on the process parameters of electrocatalytic activation of hard to recover chlorinated freons using aromatic electron transfer mediators is investigated to determine the optimal conditions for their effective implementation in production of commercially important fluoroethylenes. The process of electron-induced homogeneous catalytic polyfluoroalkylation of thiophenols is developed, which opens new opportunities of fluorinated products obtaining using cheap starting substrates - CFCs, under mild conditions in a single step with high yield.
