Abstract: | This overview discusses the electrochemical activation of freons CF2ClCFCl2 (CFC113), CF3Br (FC13B1), and CF2Cl2 (CFC12) using various electron transfer mediators: complex nickel(ii) compounds with nitrogen-containing tetradentate ligands and bipyridyl, aromatic derivatives (perylene, p-dicyanobenzene, Å-azobenzene, and others), and sulfur dioxide. A possibility was shown of the homogeneous catalytic activation of freons by two mutually supplementing electron transfer mediators: methylviologen—SO2 and I2—SO2. The involvement of freons by the electron transfer mediators into the syntheses of valuable organic products under mild conditions was demonstrated for several examples. |
