“…One of the promising solutions for these problems may be the use of Freons as valuable raw materials for the preparation of various fluorine-containing organic compounds by incorporating them as fluoroalkyl groups in organic substrates, in particular in phenols, thiophenols, pyrroles, etc. [4][5][6], or dehalogenating Freons to obtain commercially important products. Of particular interest is the joint conversion of Freons with such "small" molecules as SO 2 , CO 2 , etc., atmospheric contaminants, to obtain various fluoroalkylsulfinic and carbonic acids.…”

FOREWORDWe begin this paper by celebrating the 75th birthday of the important physical chemist and excellent human, our instructor and teacher, Academician of the National Academy of Sciences of Ukraine, Vice-President of the National Academy of Sciences of Ukraine, and honored director of the L. V. Pisarzhevskii Institute of Physical Chemistry of the National Academy of Sciences of Ukraine, V. D. Pokhodenko, with whom it has been my good fortune to work for more than 40 years, beginning at the student's bench, and largely thanks to Vitalii Dmitrievich, under his leadership and constant encouragement I understood scientific work and covered the difficult stages of the scientific life. To him I owe my sincere thanks.In continuation many years of close cooperation and daily association with V. D. Pokhodenko I did not cease to be surprised by his natural talent, his broad erudition and his sense of novelty in science, his excellent organization ability, his extremely high output and efficiency, his constant scientific research, initiating and encouragement of the ideas of scientists and co-workers, his great intelligence, sensitivity and delicacy, coupled with an exacting regard for people.V. D. Pokhodenko belongs to the pleiad of those brilliant and prominent scientists for whom scientific phenomena are their basic aims, the principal meaning of life.Thanks to V. D. Pokhodenko, the L. V. Pizarzhevskii Institute of Physical Chemistry, National Academy of Sciences of Ukraine has in recent times carried out a wide range of new and timely scientific directions, in particular studies in the fields of the physical chemistry of nano-sized systems and nano-composite materials, nanophase phenomena, nanophotocatalysis, 0040-5760/11/4606-0399 "Green Chemistry" and many others. The present papers falls within the investigation of "Green organic electrochemistry" which is developing rapidly at present.

“…For instance, Hu et al developed a procedure for the radical addition of 65 to alkenes using iron powder and catalytic amount of Cp 2 TiCl 2 or alkynes with a (NH 4 ) 2 S 2 O 8 /HCOONa redox system (Scheme ) . Arenes can also be decorated with the 2‐bromotetrafluoroethyl group originating from 65 through radical pathways . However, similarly to other dihalotetrafluoroethanes, the chemistry of 65 as a building block has recently been reviewed and will be omitted in this work.…”

In this review, we provide a comprehensive and critical perspective on the synthesis and application of 1,1,2,2‐tetrafluoroethyl‐ and tetrafluoroethylene‐containing compounds. These structures have been the focus of increasing attention as witnessed by a spectrum of new synthetic approaches, which have recently appeared in the literature. Likewise, applications of molecules containing the CF2CF2 fragment as pharmaceuticals, agrochemicals, pesticides, and advanced materials are described. It is expected that the number of successful applications of these compounds will increase in the future as a result of availability of the synthetic methods outlined here.

“…Polyfluoroalkylation of para -substituted phenols 148 by BrCF 2 CF 2 Br, activated by sulfur dioxide, afforded the corresponding ortho -CF 2 CF 2 Br derivatives 149 . In the case of phenol, the reaction led to a mixture of ortho - and para -isomers . Polyfluoroalkylation of 2,6-di- tert -butylphenol 150 resulted in the formation of highly substituted derivative 151 in 59% yield (Scheme ) …”
